Asa Gray

Asa Gray (born November 18, 1810 in Paris , New York , † January 30, 1888 in Cambridge , Massachusetts ) was an American botanist . Its official botanical author's abbreviation is " A.Gray ".

Live and act

Youth and education

Asa Gray was born in Paris in the Sauquoit Valley, New York State , in 1810 . The family's ancestors were of Scottish-Irish descent and had come to the Sauquoit Valley from Massachusetts and Vermont. He was the eldest of the eight children of the married couple Moses Wiley and Roxana Howard Gray. His father was a farmer and also works as a tanner.

Like his siblings, Asa Gray was first homeschooled and then attended school in Sauquoit. At the age of twelve, he moved to high school in Clinton County, New York, and then attended Fairfield Academy in Fairfield, Herkimer County for four years .

His interest in science was sparked by teaching with James Hadley, a professor of medicine and chemistry at Fairfield Medical School, who also taught at Fairfield Academy. That's why Gray attended lectures at Fairfield Medical School again and again during his time at the Academy. At first he was mainly interested in mineral studies , but he only became aware of botany as his later field of activity in the winter of 1827/28 through the corresponding article in the Edinburgh Encyclopædia by David Brewster . After he had succeeded in identifying the first plants independently with the help of Amos Eaton's botanical handbook, he became an enthusiastic plant collector. He used the long summer vacation for botanical and mineralogical excursions to various areas of New York State.

His father recognized Asa's natural science talent and lack of interest in the profession of a farmer and enabled him to attend Fairfield Medical School from 1829. During his time as a medical student, Gray put on an extensive herbarium and a collection of minerals. Already during this time there was close contact with the doctor and botanist Lewis Caleb Beck from Albany and the botanist and chemist John Torrey from New York, who in turn introduced him to other botanists. In February 1831, he graduated from Medical School as a Doctor of Medicine, but never practiced as a doctor.

Professional background

After graduating from medical school, Gray initially taught chemistry, mineralogy, geology, and botany at Bartlett's High School in Utica . In June 1832 he gave his first botany lecture at Fairfield Medical School, shortly thereafter he gave seminars in botany and mineralogy at Hamilton College. The fees for his teaching activities enabled him to go on botanical excursions to Niagara Falls and other locations in the states of New York and New Jersey .

In the fall of 1833 he accepted John Torrey's offer to work as his assistant at the New York College of Physicians and Surgeons. Since Torrey was a professor of chemistry, Gray had to work in his chemical laboratory, but the real interest of the two scientists was botany. In 1834, Gray's first scientific publication appeared, dealing with mineralogy. His first purely botanical work was published in 1835 together with Torrey Monograph of the North American Species of Rhynchospora.

Asa Gray (around 1841)

Torrey was only able to employ Gray as an assistant until the spring of 1834 because he lacked the necessary financial means. Gray therefore initially taught again at Bartlett's High School, with plans to return to New York at Torrey's chair after the summer break. Torrey had to refuse him again because he still lacked funding for an assistant position, but in 1836 gave him a position as curator and librarian at the Lyceum of Natural History . In his spare time he worked on his first textbook, the Elements of Botany , which he published in 1816. He also worked with Torrey on the Flora of North America. In the summer of 1836 he took a position as a botanist on the planned United States Exploring Expedition to the South Pacific under the direction of Charles Wilkes . Since the start of the expedition was delayed again and again, he used the time to do initial work on the botanical plant North American Flora, which Torrey had planned for a long time . When Wilkes' expedition finally left in 1838, Gray resigned from his position as a botanist and instead resumed a position as a research assistant with John Torreys in New York.

In 1838 he was appointed professor of botany at the newly founded State University of Michigan. Gray negotiated that he could spend an academic year abroad first before taking up the position. First, together with Torrey, he completed work on the Flora of North America , the first volume of which appeared in two parts in July and October 1838. In November he went on a trip to Europe to visit the important herbaria in which he wanted to study the extensive collections of American plants. He traveled to England, Scotland, France, Germany, Switzerland, Italy and Austria and studied, among other things, the herbaria in Padua, Berlin and Glasgow. On the trip he met some of Europe's leading botanists personally, including Archibald Menzies , Augustin de Saint-Hilaire , Robert Brown , William Jackson Hooker and Augustin-Pyrame de Candolle . He also made first contacts with numerous younger colleagues such as Alphonse Pyrame de Candolle , Joseph Dalton Hooker and Joseph Decaisne , which he maintained throughout his life.

In November 1839 he returned to America, but did not take up the professorship in Michigan because of disagreements with the university. Instead, he continued to work in New York at Torrey to publish the third and fourth parts of the first volume of the Flora of North America in June 1840 . The second volume was completed in 1843. The first part of the second volume appeared in May 1841 and the second in April 1842.

Work at Harvard

Asa Gray's home in the Cambridge Botanic Gardens

During a visit to Benjamin Daniel Greene (1793-1862) in Cambridge in 1843 , his father-in-law Josiah Quincy , President of Harvard College, Asa Gray offered the newly established Fisher Professorship in Natural History at Harvard. Gray agreed and took up the professorship that same year.

Gray had to build up the botanical department from the ground up; when he arrived Harvard had neither a botanical library nor a herbarium. The botanical garden was founded in 1805; the first director was the botany professor William Dandridge Peck. After his death in 1822, a new director could not be appointed for financial reasons, so that Thomas Nuttall, a lecturer in botany, was appointed as curator. He quit the position in 1833, since then the garden had only been looked after by a gardener, but no longer had a scientific director.

Gray moved into a small house in the botanical garden. After his arrival, Gray first set about building a library and laying out a herbarium. Although he received only a modest salary, he was able to build up an extensive literature collection within a short period of time, which he initially kept in his own house.

Since Gray feared that the herbarium and his library could be destroyed in a fire in his house, he offered to hand them over to Harvard University in 1864 if the latter agreed to build a separate building for it. The Harvard board of directors accepted the offer and had a small extension built on the house where Gray lived, a little later this was also expanded to include a small library. When it was handed over to the university in 1865, the library contained around 2,200 titles, the herbarium contained around 200,000 plant samples. By his death in 1888, Gray had nearly doubled the number of samples in the herbarium. It was the largest herbarium in the USA, and there were only a few larger herbaria in Europe.

Relationship with Charles Darwin

In contrast to his zoologist colleague at Harvard Louis Agassiz , Gray supported Charles Darwin's theory of evolution from the start , with whom he later became a lifelong friend. They first met in Kew ; they had introduced each other to Joseph Dalton Hooker . When Darwin read Alfred Russel Wallace 's thoughts on natural selection, he exchanged ideas with Gray about Wallace and his own ideas. Gray organized the first publication of Darwin's major work On the Origin of Species and administered its royalties in the United States. Darwin dedicated his book Forms of Flowers (1877) to Gray . Gray, however, was not a complete supporter of Darwin's theory of evolution, but rather saw the work of higher powers in nature in accordance with his religiosity .

Late life and death

Asa Gray's grave in Mount Auburn Cemetery

After 30 years of activity, Gray withdrew from teaching and in the herbarium in 1873, but retained his professorship for botany. From then on he devoted himself even more intensively to the writing of botanical publications and began to work on a continuation of the Flora of Northern America . In doing so, he wanted to complete the work on the one hand, but also to update the thirty-year-old part on the other.

In October 1887 Gray returned from a trip to Europe, on which he had studied the herbaria of the Kew Gardens in London and the Lamarck Herbarium of the Jardin des Plantes in Paris. After his return he continued to work on the flora . From November 28, 1887, Gray suddenly suffered from paralysis and was only temporarily conscious in the weeks that followed. He died on January 30, 1888 and was buried on February 2, 1888 in Mount Auburn Cemetery , Massachusetts.

Honors

The plant genus Grayia Hook is named after Asa Gray . & Arn. from the Amaranth family (Amaranthaceae) and Asagraea Lindl. from the Germer family (Melanthiaceae).

In 1835 Gray was elected a member of the Leopoldina . In 1848 he was accepted into the American Philosophical Society . From 1855 he was a corresponding member of the Prussian Academy of Sciences and from 1862 of the Russian Academy of Sciences in Saint Petersburg . The Bavarian Academy of Sciences accepted him as a foreign member in 1859. In 1863 he was a founding member of the National Academy of Sciences . In 1868 he was elected a corresponding member of the Göttingen Academy of Sciences . In 1873 he was accepted as a foreign member of the Royal Society and in 1878 as a corresponding member of the Académie des Sciences . In 1879 he became an Honorary Fellow of the Royal Society of Edinburgh . The magazine Asa Gray Bulletin (1893-1901, 1952-1961) is named after him, as well as the Gray Herbarium and Grays Peak , a mountain in the US state of Colorado . Since 1984, the Asa Gray Award , the highest award of the American Society of Plant Taxonomists , has been given to deserving botanists.

In 2011, the US Postal Service issued a stamp with a portrait of Asa Gray as part of a series of stamps honoring Honorable Scientists. The stamp also shows the winter leaf ( Shortia galacifolia ). Gray discovered this plant, which occurs only in the states of North Carolina , South Carolina and Georgia , on his first trip to Europe in a herbarium in Paris and described it botanically together with Torrey. Gray had failed to find a living plant of this species for nearly 40 years. It was not until 1877 that a youth from North Carolina sent him a copy.
