Famous Men of Science
One day in autumn, as he was examining some plants in the Academical Garden, a venerable clergyman, Dr. Olaf Celsius, saw him, and asked him where he came from, how long he had been at the college, and what he knew about plants. He, too, was interested in botany, and was preparing a work on the plants mentioned in the Bible. Perhaps something in Carl's face or manner touched the minister's heart, for he asked him to go home with him, and soon offered him board in his own house, and gave him access to his valuable library.
The tide of adversity was beginning to turn. Some pupils were obtained, and a little money flowed into the empty pockets. At twenty-two, by a close examination of the stamens and pistils of flowers, he decided upon a new method of arrangement by the sexes of plants, which, in after years, became the basis of his great fame. This procured him the appointment of Assistant Lecturer to Dr. Rudbeck in the Botanical Garden, where, but a year before, he had asked to be the gardener!
He still had little money, but, what was equally useful, some leisure time. He began his great works, which were not completed for seven years, "Bibliotheca Botanica," "Classes Plantarum," "Critica Botanica," and "Genera Plantarum," "letting," as he said, "not a minute pass unoccupied during his residence at Upsala. For the latter work he examined the characters of eight thousand flowers."
Scarcely had he begun this valuable labor, when the envy of one of the professors became as hard to bear as his previous poverty, and, through friends, he obtained an appointment to study the natural history of Lapland. It was a hazardous expedition for a young man of twenty-five. Now he climbed steep rocks, "which," he says, "broke loose from a spot which my late guide had just passed, and fell exactly where I had been, with such force that it struck fire as it went." Once, when floating down a river, the raft parted in the middle, and he narrowly escaped drowning. "All my food," he says, "in those fatiguing excursions, consisted, for the most part, of fish and reindeer's milk. Bread, salt, and what is found everywhere else, did but seldom recreate my palate." He travelled nearly four thousand miles, mostly on foot, often through bogs and marshes, with the water to his knees, yet always cheerful, always enthusiastic. On presenting his report to the University, on his return home, they gave him about fifty dollars for his travelling expenses for five months!
A single incident shows the tender heart of the young explorer. Very few birds were visible except the ptarmigan. He says: "The little Alpine variety of the ptarmigan was now accompanied by its young. I caught one of these, upon which the hen ran so close to me that I could easily have taken her also. She kept continually jumping round and round me, but I thought it a pity to deprive the tender brood of their mother; neither would my compassion for the mother allow me long to detain her offspring, which I returned to her in safety." Tenderness to animals seems to be a striking characteristic of great men and women.
During the journey, he found a modest little flower in the great northern forests, in the moss, and this he named Linnæa borealis, thinking it was so like himself, expanding in obscurity. He chose for his motto, Tantus amor florum, "So great is the love for flowers."
On his return to Upsala, he began courses of private lectures in medicine, but so bitter was the envy of the before-mentioned professor that the archbishop was prevailed upon to prohibit private lectures. Thus deprived of a livelihood, Linnæus turned his attention to mineralogy, visiting the Swedish mines. The Governor of Dalecarlia was so pleased with him that he engaged him to investigate the productions of his country. Here he fell in love with the daughter of John Moræus, a well-to-do physician.
Sara Elizabeth reciprocated the affections of the young man, who was told by the father that he must wait three years for a final answer; for, in truth, Linnæus's financial prospects were not bright. The University of Upsala did not want him, and there seemed to be no hope of writing or publishing his books on botany. But a man usually achieves little, who does not fight his way at every step. Now, indeed, for love's sake he must make his mark.
After saving about seventy-five dollars, he decided to go to Germany, and take his doctor's degree; but first he must visit his home, out of which his beloved mother had gone at forty-five. "Alas! alas, my mother!" was all he could say, as the tears fell fast upon her grave. She had witnessed his poverty and his heroism; she was not to witness his great renown.
At Hamburg he spent a month, receiving civilities from many scientific men. He showed his good sense in feeling in no wise humiliated because he was poor, a valuable lesson for poor young men and women to learn. At Leyden, good fortune came to him. Dr. Gronovius was so pleased with the manuscript of his "Systema Naturæ" that he requested to publish it at his own expense. By his advice, Carl waited upon the celebrated physician, Boerhaave, and after eight days gained admittance. So famous was this man that when the Emperor of China sent a letter to "Boerhaave, the famous physician in Europe," it easily reached him. He advised a rich banker, Mr. Clifford, to have Linnæus describe his magnificent collection of plants, and to send him to England and elsewhere, to collect specimens for him. This was indeed a blessing. "Here in England," he says, "I lived like a prince, and had one of the finest gardens of the world under my inspection." A society in Amsterdam advanced the money to pay for the plates for his "Flora Lapponica," and fame seemed really to be coming at last.
In his visit to England, Sir Hans Sloane, who founded the British Museum, looked upon him coldly because he had suggested a different system in natural history from his own! At Oxford, Dillenius said to friends, sarcastically: "See, this is the young man who confounds all botany!" Linnæus felt hurt, and, when about to take his departure from the city, asked the scientist why he had treated him thus. After the young student had explained his work, Dillenius became his warm friend, and pressed him to stay, and even to share his salary with him. Linnæus was greatly pleased with London, and when he saw the golden furze in its green leaves, fell on his knees before it.
On his return to Germany he went to the death-bed of Boerhaave, whose parting words were: "I have lived out my time and done what I could. May God preserve thee, from whom the world expects much more! Farewell, my dear Linnæus!"
He now hastened to the idol of his heart in Sweden, and what was his amazement to find that the friend to whom he had intrusted his correspondence with Sara Elizabeth had been trying to win her for himself! Perhaps it would have been quite as well for Linnæus had he succeeded! However, matters were amicably adjusted, and the long waiting lover became engaged.
He repaired at once to Stockholm to begin the practice of medicine, still keeping as near Upsala University as possible. And here troubles began anew. He says: "Being unknown to everybody, people were unwilling to trust their lives in my hands. Nay, they even hesitated to trust me with their dogs! Abroad, I had been honored in every place as Princeps Botanicorum; but in my own country I was looked upon as a Klim, newly arrived from the subterranean regions! No one cared how many sleepless nights and toilsome hours I passed. Had I not been in love I would certainly have left Sweden and gone abroad."
After a time a fortunate cure effected by him brought him speedy popularity. "No invalid could now recover without my assistance. I was busy from four in the morning till late in the evening; nor were my nights left undisturbed." He was soon chosen a member of the Upsala Academy, and at the request of the king, through his tutor, Count Tessin, gave public lectures on botany and mineralogy.
And now the rising botanist desired to claim his bride. They were accordingly married June 26, 1739, when Linnæus was thirty-two. Dr. Moræus had waited long enough to see that his daughter was making no mistake. Life now flowed on smoothly. If the "little wife," as he called her, governed him with no very gentle sway in after years, she had great influence over him, and it is said that at her instigation he persecuted his only son. All the more is Linnæus to be admired for accomplishing such a grand work with domestic hindrances. It takes a very great man to be great when his home is not a help to him! However, he always regarded her as "one of the choicest gifts bestowed upon him."
His medical practice brought him plenty of money, but he wrote to a friend: "Once I had plants and no money: now what is money good for without plants?" Soon the desire of his heart was granted, and he was made Professor of Botany at Upsala University, also superintendent of the Botanical Garden.
Now he says: "I render thanks to the Almighty, who has ordered my lot so that I live at this day; and live, too, happier than the King of Persia. I think myself thus blessed because in this academic garden I am principal. This is my Rhodus, or, rather, my Elysium; here I enjoy the spoils of the East and the West, and, if I mistake not, that which far excels in beauty the garments of the Babylonians and the porcelain of China."
His fame grew rapidly. He published, in 1745, his "Flora Suecica," and a year later his "Fauna Suecica," a description of Swedish plants and animals. His lectures soon, by their enthusiasm and eloquence, brought listeners from all parts of Europe. The number of students in the university grew from five hundred to fifteen hundred, young men coming even from America to hear the great botanist. During the summer he made excursions twice a week, often at the head of two hundred students, and when some rare plant was discovered, the news was announced to the others by horn or trumpet. His scholars, imbued with his spirit, went over the world in scientific investigation. Some died in the Arabian deserts; some in the swamps of Africa. From foreign students he would take no fee, as he desired to show them how he loved his work. Once he said to a German student: "Tell me, candidly, are you rich, and can you afford it? If you can, then give the money to my wife; but, if you be poor, so help me Heaven, I will not take a single farthing from you!"
Most of the scientific societies of Europe made him a member after his great works were published. The Imperial Academy called him "Dioscorides Secundus"; a gold medal was struck in his honor in 1746, and the king made him dean of the College of Physicians. He published two valuable medical books, and received the honor of the Knight of the Polar Star, never before conferred for literary merit. He was made a noble, and took for his motto, Famam extendere factis, adorning his crest with the little flower which he discovered in his poverty. He was made rector of the university, holding the position for several years. How different from the time when he could obtain only a chance meal, and covered up the holes in his torn shoes!
He bought two estates, living at one of them – Hammerby – for fifteen years. In 1774, when he was sixty-seven, he suffered an attack of apoplexy in the Botanical Garden, and, two years later, another stroke made him a paralytic. When he could no longer walk, he used to be carried to his museum, and look long and earnestly at his treasures, gathered from every clime. His memory so failed him that he mixed the Greek and Latin letters, and forgot even his own name. On the 10th of January, 1778, death came to him in his sleep.
The university went into mourning, the king made a public address, and the whole nation regarded it as an irreparable loss. His herbarium and library were sold, after a time, by the wife, to Sir James E. Smith, the founder of the Linnæan Society, of London, where these treasures are now to be seen, and most of the one hundred and eighty works which he published during forty-five years. It is said that the King of Sweden, on learning that the work of Linnæus was going out of the country, sent a man-of-war to recover it, but without avail.
Linnæus was small in body, with large head, and the bright, piercing eyes which usually characterize men and women of genius.
Of his six children, the oldest soon became professor of botany, to assist, and then succeed, his father, but he lacked the parent's just and honorable love of fame. The eldest daughter inherited much of his ability, being the first to discover the luminous property of the nasturtium flowers at night. Sara Elizabeth survived her noble husband many years, and now lies beside him in the cathedral.
BARON CUVIER
In the town of Montbéliard, France, then belonging to the Duke of Würtemberg, August 23, 1769, was born the founder of the Science of Comparative Anatomy; the greatest naturalist of his time, Georges Léopold Chrétien Frédéric Dagobert Cuvier. His father was a brave officer in a Swiss regiment, who at fifty married a young lady of unusual ability. Their first son died, and the second, Georges, was so feeble in constitution that his life was saved only by the tenderest care of his mother.
For this mother the boy cherished the most ardent affection. While she lived, there was nothing left undone that a loving nature could do for her. When she died, everything connected with her memory became sacred. When Cuvier had become honored by kings and nobles, when the great from all the world delighted to bring him offerings, nothing so touched his heart as the gift of a bouquet of red stocks, her favorite flower. Perchance the benignity that came into his face in later years was the result of these sweet remembrances.
She taught him to read at four, and, though ignorant of Latin, she made him repeat his lessons to her daily, so that he was the best prepared of any boy in school. She read to him history and general literature. She made him draw under her inspection. She talked with him about books till a passion for reading became the chief characteristic of his nature. No wonder that he loved such an inspiring woman. The history of most great men emphasizes the fact that the mothers cannot be too highly educated. At ten years of age he was placed in a high school, called a Gymnase, where for four years he studied Latin, Greek, history, geography, and mathematics, and was constantly at the head of his classes. Naturally enthusiastic, he played as heartily as he studied.
As is often the case, a book turned the course of his life, and made him famous. At the Gymnase he found a work of Gesner, the Swiss naturalist, and this, with its colored plates, first turned his attention to natural history. This liking was intensified by finding at the house of a relative the complete works of Buffon, the noted naturalist, who wrote thirty-six volumes in his own brilliant and poetic style, describing the animal kingdom. The boy became intensely interested in the habits of quadrupeds and birds; their form, their color, and their homes. He copied the illustrations in the work, and colored them with paint or pieces of silk. He always carried a volume of Buffon in his pocket to read when he had a moment of leisure. At twelve, he was a well-read naturalist.
In his last year in the Gymnase, when he was fourteen, he chose a certain number of his school-fellows, and formed an Academy. Every Thursday he gathered the lads into his room, and placing them around a table, seated himself upon his bed, and after some book had been read on natural history, philosophy, history, or travels, he asked their opinions of it, and then, being president, summed up the argument in a clear and concise manner. The mother's seed-sowing in the mind of her ardent boy was bearing fruit.
As the family were poor, and had only a soldier's pension to support them, it was decided that Georges should enter the free school at Tübingen, and prepare for the church. But the principal of the Gymnase, who had never forgiven the boy for some playful trick, placed his composition in the third rank. Georges knew that it deserved the first rank, and that this low standard would affect his position in college. He, therefore, resolved not to enter Tübingen, and, though he was thereby lost to the church, he was saved for great scientific work.
A fortunate thing now happened. A woman, a princess, who knew about the bright boy, spoke of him to her brother, Duke Charles of Würtemberg. When the duke visited Montbéliard, he sent for the lad, questioned him as to what he had learned, asked to see his drawings, and ended by sending him free of expense to the University of Stuttgart, to enter his own Academy, called the Academy Caroline. It seemed a little thing for a lady to speak of a boy's studiousness and great love of books, but it proved a great thing for Georges Cuvier and for the scientific world. Thousands of women and men could do more of these little acts of kindness, if they only thought of it. Well said Thomas Hood: —
"Evil is wrought by want of thought,As well as want of heart."The boy of fourteen said good-by to his devoted mother, and started for Stuttgart, seated between the Chamberlain and the Secretary of the Grand Duke. Both spoke German all the way, and the lonesome boy did not understand a word. He entered the Academy May 4, 1784, and for four years studied mathematics, law, philosophy, finance, and the like.
But he lost no opportunity to study natural history. A professor gave him the works of Linnæus, and he gained inspiration from the young man who could travel four thousand miles through the marshes of Lapland, nearly barefoot and half-starved, in his study of plants. Georges now collected a herbarium. When he had leisure, he drew and colored insects, birds, and flowers with great accuracy. He kept a number of living insects in his room, constantly feeding them, and watching their habits. He said years afterward, "If I had not studied insects from choice, when I was at college, I should have done so later, from a conviction of its necessity." He declared that the wonders he met with in the organization of insects always elevated his thoughts.
Nine months after his arrival in Germany, he won the prize at the Academy for excellence in the German language, receiving the order of Chevalerie, an honor given only to five or six out of four hundred pupils. This entitled the recipients to dine at a separate table, and to enjoy many advantages under the immediate patronage of the Grand Duke.
When the four years of college life were over, the father's pension having ceased on account of the disturbed financial condition of France, the youth of eighteen needed to find employment at once. Nothing seemed open to him but the position of tutor in a private family, a thing much deprecated by his school-fellows, who had already built many air-castles for his future.
But young Cuvier had the courage and the wisdom to do what necessity required, and to do it cheerfully. In July, 1788, he entered the family of Count d'Héricy in Caen, Normandy, and for six years taught his only son. He took with him, says a friend, "these admirable foundations for glory: a love of labor, depth of reflection, perseverance, and uprightness of character." While teaching here, he met the nobility of the surrounding country, increasing thereby his polish of manner and tact, for which he was celebrated all his life.
Living by the sea, he was led to study marine animals. The casual dissection of a calamar, a species of cuttle-fish, influenced him to study the anatomy of mollusca, which afterward led to his great classification of the whole animal kingdom. In this obscure corner of Normandy, the young teacher observed, and committed his observations to paper. Some young men would not have found time for such work. Those only succeed who have sufficient force of character to make time for what they wish to do. To allow one's time to be wasted, is to allow one's opportunities for eminence to go by forever.
Nearly every evening Cuvier attended a small society of which he was secretary, which gathered chiefly to discuss agricultural and kindred topics. M. Tessier, living there in exile under an assumed name, the author of several valuable articles in the Encyclopedia, was often present, and between him and the young secretary a warm friendship soon existed. As the friendship of the Marquis Guidubaldo proved valuable to Galileo, so that of M. Tessier proved of great benefit to Cuvier. He led the young and comparatively unknown naturalist, though some of his articles had been published in learned journals, to correspond with Geoffroy St. Hilaire, De Lacépède, and others on scientific subjects. Through their influence he was finally called to Paris, made a member of the Commission of Arts, and professor at the Central School of the Panthéon.
He was only twenty-six, and this was but the beginning of honors. Here he composed his "Elementary Treatise on the Natural History of Animals." His great desire was to be attached to the Museum of Natural History, where he could study the collections and enlarge them. Very soon after his arrival in Paris, M. Mertrud was appointed to the newly created chair of Comparative Anatomy at the Jardin des Plantes. He was advanced in years. And now came the opportunity for friendship to do its work. Geoffroy St. Hilaire and De Lacépède were his colleagues. They urged that their friend Cuvier be appointed assistant, and Mertrud gladly consented. This was indeed an honor, since Daubenton, Buffon, Lamarck, and other European celebrities had filled this position.
Cuvier at once sent for his aged father, now nearly eighty years old, and his only brother, Frédéric, to make their home with him. The precious mother had died two years previously. She did not live to see the fame of her eldest son, but she must have been convinced of his future greatness, and been comforted by the prospect.
From the moment of entering upon his new work, Cuvier began to develop that wonderful collection in comparative anatomy which is now so celebrated. Nothing ever turned him from his purpose of making this the most extensive collection in the world; no sorrow, no legislative duties, no absence. No one who has visited Paris will ever forget the seventy-five acres in the Jardin des Plantes, with trees and flowers from all the world; with thirteen rooms filled with skeletons and anatomical preparations of all kinds; with eleven rooms in the gallery of anthropology containing every variety of the human species, in casts, mummies, and fossils; with the gallery of zoölogy containing over two thousand mammalia, belonging to five hundred species, as many reptiles, ten thousand birds, and over twenty-five hundred fishes; with immense geological, mineralogical, and botanical collections; all a marvel of industry and learning.
Cuvier now worked unceasingly. Sometimes his salary was in arrears, but he bore it cheerfully, as he wrote a friend: "You are not to suppose that Paris is so highly favored; for twelve months' pay are now due at the Jardin des Plantes, and all the national establishments for public instruction, in Paris as well as at Strasburg; and if we envy the elephants, it is not because they are better paid than we are, but because while living on credit, as we do, they are not aware of it, and consequently are insensible to the pain it gives. You know the saying about the French, that when they have no money they sing. We savants, who are not musicians, work at our sciences instead of singing, which comes to the same thing." He is a hero, indeed, who can breast poverty, and work and sing in the midst of hardship. When he published his "Annals of the Museum," he not only drew, but often engraved the plates himself, when he was unable, for lack of means, to hire it done.
The National Institution was founded in 1796, and Cuvier was associated with his friends De Lacépède and Daubenton, in the section of zoölogy, holding the position of Secretary of Natural Sciences till his death.
Four years later, in 1800, the first two volumes of his "Lessons in Comparative Anatomy" were published, and met with great success. The last three volumes were issued five years later.
In this year, 1800, Cuvier received another honor, that of the professorship of Natural Philosophy in the Collège de France. He was now but thirty-one. The following year, Napoleon I., who was usually wise in his selection of men, appointed him one of the six inspectors-general of education, to establish public schools in thirty towns of France.
