Benjamin Dann Walsh (September 21, 1808 – November 18, 1869) was an English-born American entomologist who served as the first official state entomologist in Illinois.[1] He was a leading influence during a time of significant transition in American entomology. Walsh championed the application of scientific methods to control agricultural pests. He was a proponent of biological control as an effective means to manage insects. He was also one of the first American scientists to support Charles Darwin's theory of evolution and was instrumental in securing its broad acceptance in the entomological community.[2]
