Adolph George Germany Schulz was an AllAmerican American football center for the University of Michigan Wolverines from 1904 to 1905 and from 1907 to 1908. While playing at Michigan, Schulz is credited with having invented the spiral snap and with developing the practice of standing behind the defensive line. As the first lineman to play in back of the line on defense, he is credited as footballs first linebacker.

The couple emigrated from Germany to the United States in 1880 with their infant daughter Wilhelmina . Schulz also had two brothers, Fred Schulz and Arthur Schulz, both of whom became doctors. Schulz played football for Fort Wayne High School and was also a member of amateur city teams for several years.
