John Edward Dinsmore (1862–1951) was a botanist and educator, born in Maine, United States.

[1] In 1898, Dinsmore moved with his wife and daughter to Jerusalem,[2] to join the American Colony — a Christian utopian society which had been founded seventeen years earlier in 1881 by Anna and Horatio Spafford.

[5] Collections are also held at the National Herbarium of Victoria at the Royal Botanic Gardens Victoria,[6] Harvard University Herbaria, the herbarium at the Royal Botanic Gardens, Kew, and the Swedish Museum of Natural History.

Dinsmore produced several publications, including The Genus Iris in Syria and Palestine (1933)[3] and a substantial revision of Post's Flora of Syria, Palestine and Sinai.

Published in 1932-33 and containing both Latin and Arabic names,[7] this volume remains the standard botanical reference for the region.
