E. F. Warburg

Edmund Frederic ("Heff") Warburg (22 March 1908 – 9 June 1966) was an English botanist, known as the co-author of two important British floras.

Warburg was born in London on 22 March 1908, son of Sir Oscar Emanuel Warburg, businessman and later chairman of the London County Council, and his wife, Catherine née Byrne. His father was a member of the distinguished German–Jewish Warburg family that included botanist Otto Warburg and Otto Heinrich Warburg the Nobel Prize–winning physiologist.

His father was an enthusiastic amateur botanist, and the garden of their house at Headley, Surrey, contained a large collection of plants, particularly Cistus, Berberis, and oaks. Warburg went to school at Marlborough College, then won a scholarship in mathematics to Trinity College, Cambridge. He transferred to natural sciences and was subsequently elected a senior scholar. In 1930 he was awarded a first class in part two of the natural sciences tripos, with botany as his main subject.

While still an undergraduate, he went on a botanical expedition with Tom Tutin and others to the Azores, some results of which they published in 1932. Warburg was responsible for the introduction to cultivation of Daboecia cantabrica ssp. azorica, a plant new to science. He was also at this time developing his lifelong interest in the bryophytes. Before graduating, Warburg collaborated with his father in writing an account of the genus Cistus. Meanwhile, he prepared a thesis on the cytotaxonomy of the Geraniales, on the strength of which he was made a research fellow of Trinity in 1933 and was awarded his PhD in 1937. He was elected as a fellow of the Linnean Society in 1934.
