Frederick Knab (September 22, 1865 – November 2, 1918) was an artist and entomologist active from the 1880s through the 1918, most noted for his oil paintings and illustrations and his work with coleopterous and dipterous insects.
[1] In 1889, he went to Europe and studied art for two years at the Munich Academy, and then established a studio in Chicopee with the intention of making landscape painting his profession.
[3] In 1903 the Carnegie Institution of Washington provided a grant to United States Department of Agriculture entomologist Leland Ossian Howard to develop a monograph of the mosquitoes of North and Central America and the West Indies.
He began working on a Doctor of Philosophy degree at George Washington University, but the final stages of his illness prevented him from completing the requirements before his death.
[3] Knab died in Washington, D.C. on November 2, 1918, after a long and painful battle with leishmaniasis contracted during his expedition to Brazil in 1885–1886, which he himself diagnosed through study of the South American medical literature.
