John James Jachym had a very distinguished career in many fields, including baseball and golf. He was born in the state of Ohio on May 9, 1918, and spent a great deal of his youth growing up on a dairy farm in South Dayton. "Living on a dairy farm is one of the best ways of maturing," said Jachym.
After graduating from South Dayton, Jachym entered the University of Missouri in 1936 and graduated in 1940 with a degree in journalism. While in Missouri, Jachym competed for the Tigers in baseball.
