Having received a facelift with new stadium seating, completed in the summer of 2020 as part of the Transforming Tomorrow Campaign, Harms Stadium honors Ray and Gracia Harms. 

The Wartburg College Board of Regents approved the naming of Harms Stadium at Hertel Field to honor Ray Harms, a 1951 graduate, and his wife, Gracia. Ray was a member of the Knights baseball team and taught religion and Greek at Wartburg for 36 years, retiring in 1994. Ray died in 1998, and Gracia remained a fixture in the community until her death in 2018. The leadership gift was provided by their son, Matt Harms, a 1981 Wartburg graduate. The funds helped provide permanent seating for 500 for baseball, including 100 chair seats and improved handicap accessibility. A new press box, with technology enhancements and improved sight lines.

Hertel Field also features FieldTurf infield, installed in 2013, and is named after Dr. Elmer W. Hertel in recognition of his contributions to Wartburg athletics.
