Born Fife, 1837; died Edinburgh 1882
John Sadler joined the staff of the Royal Botanic Garden Edinburgh in 1854, working in the propagating department and herbarium before becoming assistant to Regius Keeper Professor J.H. Balfour, a post he held for almost 25 years. He was appointed curator (principal gardener) at the Garden in 1879. An inveterate rambler he gained a great knowledge of the Scottish flora, especially the flora of Perthshire, and discovered many new stations for plants, several of which perpetuate his name. Sadler lectured regularly to the Botanical Society of Edinburgh, which he served as Assistant Secretary from 1858 until 1879. Known as a genial, good natured man his many other professional and social memberships included being a founder member of the Scottish Alpine Botanical Club (1868) and Secretary of the Scottish Arboricultural Society from 1862 to 1879. An all round practical botanist, he was awarded the Neill Prize in 1869 and also lectured in botany at the Royal High School for over 20 years. In 1881 he took charge of the development of the Arboretum, then administered separately from the Garden. While engaged in planting the Arboretum in December snow he caught a chill and died at the age of 45, leaving a widow and 7 children.

Born near Callander and graduated in medicine at the University of Edinburgh. He became a physician, and succeeded Roxburgh briefly at the Calcutta Botanic Garden, but returned to Scotland to establish his right to be head of Clan Buchanan. Francis Hamilton (né Buchanan) changed his name to “Hamilton” to fulfil the requirements of a legacy. Buchanan Hamilton contributed greatly as a botanist, zoologist and geographer in India. He was the first botanist to see Pinus excelsa and Juniperus recurva.
Secretary of the Linnean Society and compiler of Index Kewensis.
Augustin Léveillé attended medical school prior to entering into the priesthood. In 1887 he travelled to India as a missionary and was then appointed a professor of natural history at the College of Pondicherry. In 1891 he returned to France for health reasons, settling in his hometown of Le Mans. Following a meeting with botanist Adrien René Franchet in 1900, he agreed to perform studies on the many thousands of plant specimens sent by collectors from the Far East. From these shipments Léveillé is credited with describing around 2000 new species with many of the plants being co-described along with Father Eugène Vaniot. In 1892 he founded the magazine Le Monde des Plantes, serving as its director until his death. During the same year he founded the Académie internationale de géographie botanique (International Academy of Botanical Geography). He published several monographs on plants collected from Japan and China as well as a dictionary of French flora in 1916. Numerous species are named in his honour, as well as the genus Leveillea (family Asteraceae). His herbarium was acquired by Scottish botanist George Forrest.
