Nicholas, John Spangler
- Charles W. Carey Jr.
Nicholas, John Spangler (10 March 1895–11 September 1963), embryologist, was born in Allegheny, Pennsylvania, the son of Samuel Trauger Nicholas, a Lutheran minister, and Elizabeth Ellen Spangler. Because his father changed parishes every few years, he grew up in a number of small Pennsylvania communities, graduating from the public high school in Middletown. In 1912 he matriculated at Pennsylvania (now Gettysburg) College with the intention of becoming a physician, but he soon developed an interest in biology. He spent the summer of 1915 studying botany and bacteriology and taught these subjects as an assistant during his senior year. He received his B.S. degree in 1916 and remained at the college as an assistant and graduate student while also teaching Latin, Greek, and English at Gettysburg Academy. After receiving his M.S. degree in 1917, he enrolled in the graduate zoology program at Yale University but left a year later to enlist in the U.S. Army Medical Corps as a private. He spent World War I at the Army Medical School in Washington, D.C., testing and preparing typhoid vaccines....
