Gordon Floyd Ferris (January 2, 1893, in Bayard, Kansas – May 21, 1958) was an American entomologist who served as professor of biology at Stanford University from 1912 to 1958 and earned a reputation for his teaching.
He founded and edited the journal Microentomology, preferring to work on insects that could only be examined on microscopic slides.
When he was young the family moved to Monticello, Missouri, where they lived in a log cabin.
His mother died when he was three and he went to live with his paternal grandparents in La Harpe, Kansas.
In his early years, he joined the Museum of Vertebrate Zoology on field trips to collect ectoparasites of mammals.
Around the 1940s he insisted that graduate students learn to read technical papers in German.
