Russ Tiedemann coached the University of Wisconsin-Oshkosh Titans from 1968-69 and 1971-88, building the program into a national power. He was at the helm for one national championship, 15 conference titles and more than 500 victories.
Tiedemann led UW-Oshkosh to 10 straight WIAC championships from 1979-88. He also guided the Titans to eight NCAA Div. III World Series appearances and three NAIA World Series visits.
In 1985, UW-Oshkosh became the first school from Wisconsin to win the NCAA Div. III Baseball World Series when it defeated Marietta College (Ohio), 11-6, in the championship game. The Titans captured the title by advancing through the loser's bracket after suffering a defeat in their opening game.
UW-Oshkosh concluded the 1985 season with a 37-3 record. Tiedemann, who recorded his 400th and 401st coaching victories at the World Series, was named NCAA Div. III Coach of the Year following his team's performance. He also was selected as the NAIA Coach of the Year in 1974.
Tiedemann concluded his 20-year baseball-coaching career at UW-Oshkosh with a 501-165-2 (.748) record.

Tiedemann saw 28 of his players sign professional baseball contracts, including Jim Gantner, who played 17 years for the Milwaukee Brewers, and other major leaguers Dorian Boyland, Terry Jorgensen, Dan Neumeier and Gary Varsho.

In 2012, he was selected the WIAC Baseball All-Time Co-Coach in conjunction with the conference's Centennial Celebration.

Tiedemann earned a bachelor's degree in education from UW-Oshkosh (1955), master's degree in education from the University of Northern Colorado (1964) and doctorate in education from the University of Utah (1971).
Following his graduation from UW-Oshkosh, Tiedemann taught and coached at Hortonville High School from 1955-60 and Rhinelander High School from 1960-65. He then returned to UW-Oshkosh in 1965 to teach physical education classes and coach basketball, baseball and football.
