Research in Mendelian heredity was first given permanent institutional support in the U.K. at the John Innes Horticultural Institution. The path by which this was achieved is described. It is shown that Brooke-Hunt in the Board of Agriculture played a decisive part in redirecting the John Innes Bequest from a school for gardeners as intended by the testator to an institute given to research on plants of importance to the horticultural trade. The choice of William Bateson as the institute's first (...) director is traced to the influence of a lobby of academic biologists led by J. B. Farmer. The effects of Bateson's appointment on the shape taken by the new institute and on its subsequent history are described. (shrink)
