S. F. Light

Sol Felty Light (May 5, 1886 – June 21, 1947) was an American zoologist, entomologist, and professor at the University of California, Berkeley, known for his research on caste development in termites in the first half of his career, and for teaching marine zoology courses in the second half. From 1913 to 1947, he published approximately 70 papers, most on the subject of entomology. His class syllabus on zoology was originally designed for students at Berkeley, but in 1941 it was published as an invertebrate zoology textbook and field guide that had larger appeal, as it was considered the first complete compendium of marine invertebrates in the north central California coastal region ever published. After Light's death, the book was edited, revised, and expanded by Ralph I. Smith and other contributors, becoming known as ''Light's Manual''. After Smith himself died, the book was renamed ''The Light and Smith Manual'' in his honor. Provided by Wikipedia
