Bernard Ogilvie Dodge (18 April 1872 – 9 August 1960) was an American botanist and pioneer researcher on heredity in fungi. Dodge was the author of over 150 papers dealing with the life histories, cytology, morphology, pathology and genetics of fungi, and with insects and other animal pests of plants. He made the first studies of sexual reproduction in the common bread mold, Neurospora. Dodge's work on the genetics of Neurospora laid the groundwork for the discoveries that earned George Wells Beadle and Edward Lawrie Tatum the Nobel Prize in 1958.
