Wilhelm Friedrich Benedikt Hofmeister (18 May 1824 – 12 January 1877) was a German biologist and botanist. He "stands as one of the true giants in the history of biology and belongs in the same pantheon as Darwin and Mendel." He was largely self-taught.
Hofmeister was the son of a book and music publisher and seller in Leipzig. He left school at the age of 15 and was apprenticed in a bookshop in Hamburg by an acquaintance of his father. He did most of his research in his free-time, largely from four to six in the morning before going to work. Nevertheless, he was only 27 when he published his ground-breaking monograph on the alternation of generations in plants. Not until 1863, he was employed as a professor. That was at the University of Heidelberg. In 1872, he moved to the University of Tübingen.
Hofmeister is widely credited with discovery of alternation of generations as a general principle in plant life. His proposal that alternation between a spore-bearing generation (sporophyte) and a gamete-bearing generation (gametophyte) constituted a unifying theory of plant evolution that was published in 1851, eight years before Darwin's On the Origin of Species.
Hofmeister was an early student of the genetics in plants. He is cited for the first studies of plant embryology. According to C. D. Darlington, Hofmeister had observed what would later be called chromosomes in a dividing cell nucleus as early as 1848. He left detailed sketches which are reproduced in Darlington's The Facts of Life, though he was not the first to observe them.
In 1869, he was elected a foreign member of the Royal Swedish Academy of Sciences.
Hofmeister's contribution to biology is still far from widely acknowledged. This may partly be attributed to the fact that only one of his works were translated from German to English. However, Kaplan & Cooke conclude that "his reputation became eclipsed because he was so far ahead of his contemporaries that no one could understand or appreciate his work".
