Henry Louis Smith (1859–1951) was the ninth president of Davidson College and the first president to not be an ordained Presbyterian minister. Originally from Greensboro, North Carolina, Smith graduated from Davidson in 1881 but returned as a professor of physics before becoming president in 1901. It was during his time as a professor that Smith and a group of students created one of the first x-ray images in America. Smith left Davidson in 1912 to become president of Washington and Lee University and in 1929 would eventually retire in Greensboro, North Carolina.
