Gilbert M. Doolittle (1846-1918) was a 19th century apiarist considered to be the father of commercial queen rearing. His book Scientific Queen-Rearing: As Practically Applied (Thomas G. Newman: Chicago, 1888) was reissued over several editions.
Doolittle also wrote several brochures on beekeeping, and submitted regular articles to Gleanings in Bee Culture over many years. His involvement coincided with a great expansion of beekeeping knowledge in the United States.
