Baker, Herbert G.

Herbert George Baker (February 23, 1920 – July 2, 2001) was a British-American botanist and evolutionary ecologist who was an authority on pollination biology and breeding systems of angiosperms. He described what became known as "Baker's rule," a theoretical proposal underpinning an empirical observation that the ability to self-fertilize improves colonization ability among plants by increasing the probability of successful establishment after long-distance dispersal. He collaborated with his wife, Irene Baker, studying the content and function of nectar, and undertaking research and publishing papers on its evolutionary and taxonomic significance.
