George Henslow was the son of John Stevens Henslow now remembered primarily as the Cambridge mentor of Charles Darwin. He was a medalist of Christ College, Cambridge, graduating in about 1858.

Like his father George was a botanist. He endorsed evolution though he promoted Lamarkism, rather than natural selection, showing that plants were capable of adapting to environmental stresses. (George Henslow on Natural Selection). In 1919 he was made vice president of the British Association for the Advancement of Science.

Francis Galton in Inquiries into Human Faculty and its Development cites some of Henslow's mental processes in ways which suggest he was a synaesthete (pp. 67, 82, 100, 115).
