Henry Horatio Dixon (born May 19, 1869 in Dublin , † December 20, 1953 ibid) was an Irish botanist (plant physiology and anatomy).
Dixon, son of a soap manufacturer, studied at Trinity College Dublin and in Bonn and became an assistant at the chair for botany in 1894 and professor for botany at Trinity College Dublin from 1904 to 1949. In 1906 he became director of the Botanical Gardens in Dublin and in 1910 of the herbarium.
Dixon dealt primarily with plant anatomy (among other things of orchids) and cytology (early studies on the cell nucleus, meiosis and mitosis). In 1894 he and the physicist John Joly developed a cohesion theory of water and mineral transport in the xylem of plants. He also developed measuring methods for the osmotic pressure in plants.
He was a Fellow of the Royal Society (1908). From 1944 to 1947 he was President of the Royal Dublin Society. In 1947 he became a member of the Royal Irish Academy . In 1950 he was honorary president of the International Botanical Congress in Stockholm in 1950.
