Biographical History

Henry Guernsey Hubbard (1850-1899), horticulturist, botanist, and entomologist, graduated from Harvard University in 1873. His interest in entomology was influenced by Hermann Hagen, Baron von Osten-Sacken, and Eugene Amandus Schwarz, who became his closest professional colleague. Hubbard and Schwarz conducted several expeditions to Michigan, collecting specimens in the Lake Superior region in 1874, 1876, 1877, and 1878. In 1877 he traveled to Jamaica to study and collect termites. He accepted a position as naturalist with the Geological Survey of Kentucky in 1879, and became interested in the fauna of caves. Between 1880 and 1889, Hubbard lived in Florida where his research was primarily concentrated on horticulture. His entomological work during these years focused on insect pests of the orange tree and he developed a kerosene emulsion as a remedy for haustellate insects. This work culminated in publication of the Department of Agriculture "Report on Orange Insects" in 1885. From 1889 to 1892, Hubbard made collecting trips to Michigan, Montana, Utah, and Oregon. He returned to Florida in 1893 to conduct investigations of the insect guests of the Florida land tortoise. In 1894 he accompanied Charles V. Riley on a collecting trip to the British West Indies. Between 1896 and his death in 1899, his health interfered with his work, although he continued to collect whenever possible.
