William Starling Sullivant.—Born in Franklinton, Ohio, Jan. 18, 1803, died in Columbus, Ohio, April 30, 1873. He was educated at Ohio University and Yale. The death of his father at the time of his graduation prevented him from studying for one of the learned professions and he became a surveyor and practical engineer, which occupation he followed until late in life. During this time he collected and studied the plants of central Ohio, and in 1840 he began to pay particular attention to Mosses; this became the subject of his special study, and he was soon recognized as the most eminent bryologist that this country has ever produced.
In 1864 the degree of LL.D. was conferred on Sullivant by Gambier College. He was elected to membership in many scientific societies both in the United States and Europe. At his death his bryological books, collections and preparations of Mosses were given to the Gray Herbarium of Harvard University. The remainder of his botanical library was bequeathed to the Ohio State University then called the Agricultural and Mechanical College. His microscopes were given to Starling Medical College. Of this institution he was senior trustee. He was the author of many new species and the plants named for him by other botanists are as follows:
- Sullivantia, a genus of the Saxifrages. The name first proposed by Gray (1840) for the species discovered by Sullivant was Saxifraga Sullivantii; two years later Gray established the genus Sullivantia and published the name of the plant in question as Sullivantia Ohionis. According to the rules of priority that name now stands as Sullivantia Sullivantii.
- Discina Sullivantii, a species of discomycetous fungi.
- Panus Sullivantii, a species of Agaricineae.

Leo Lesquereux.—Born in Fleurier, Switzerland, Nov. 18, 1806, died in Columbus, Ohio, Oct. 25, 1889. On entering the Academy of Neuchatel he met Arnold Guyot and together they became devoted to natural science. In 1822 he went to Eisenach preparatory to entering the University of Berlin, supporting himself by teaching French. He was principal of a college at Chaux de Fonds but had to give this up on account of deafness. From this time he did engraving, made watch springs, and studied Mosses and fossil plants.
In 1848 Lesquereux came to America settling at Cambridge, where he assisted Louis Agassiz; but he soon removed to Columbus, Ohio, where he lived until his death. He was a worthy associate of William S. Sullivant to whom in fact he was indebted by the most commendable generosity. He was a paleo-botanist and a student of Mosses. Many plants are named for him including a large number of fossil forms.

John Strong Newberry.—Born at Windsor, Conn., Dec. 22, 1822, died in New York, Dec. 7, 1892. He graduated from Western Reserve College 1846 and from Cleveland Medical College 1848. He studied abroad for two years and then practiced medicine in Cleveland until 1855 when he was appointed acting Surgeon and Geologist to an exploring expedition through the country between San Francisco and the Columbia River. He went on several of these expeditions studying the botanical, zoological, and geological features of the country. In 1869 he was appointed Chief Geologist to the Geological Survey of Ohio.
