Alfred Holmes "Fritz" Von Kolnitz (May 20, 1893 – March 18, 1948) was a Major League Baseball third baseman who played for three seasons.

He is in the Hall of Fame for both schools [2][3] His baseball career went on hiatus as he joined the U.S. Military to serve during the first World War.

"Von Kolnitz played a lot of baseball at Camp Gordon, and was promoted from the rank of captain to major in September 1918, making him the highest ranked former major league player in military service during the First World War," Gary Bedingfield wrote for the Baseball's Greatest Sacrifice website [4] According to Bedingfield, after the war Von Kolnitz worked in the real estate and insurance fields and was an author on historical matters.

When World War II broke out, he re-entered the service, eventually earning the rank of Lt.

In September 1943, Von Kolnitz was awarded the Legion of Merit for perfecting a sand-table that he used to familiarize his air crews with their targets.
