Glenn Leonhart, 93, a former longtime Oak Park resident, died peacefully at home in Redmond, Washington, on Feb. 20, 2022, surrounded by Marilyn, his wife of 65 years, and his family.

Trained in industrial design, he was self-employed as a furniture designer, highly sought after for his custom executive office suites. During the early years of the restoration of the Frank Lloyd Wright Home & Studio, he was called upon to make renderings for a project to restore some of the original Wright-designed furniture for the Oak Park house museum.

“He never used autoCad,” recalled one of his daughters. “Everything in his work was done by hand, very old school.” 

He also had a passion and talent for gardening and inspired a love of gardening in his daughters as well as grandchildren.

Born in September 1928 to Lala and Arthur Leonhart in Oklahoma City, Oklahoma, he graduated in 1946 from Classen High School, served in the U.S. Army in Korea from 1946-48 and was an officer in the Army Reserve from 1948-56. 

He earned a Bachelor of Interior Architecture degree in 1953 from Oklahoma A&M (now Oklahoma State University), where he was a member of Sigma Phi Epsilon. He earned a Master of Industrial Design in 1956 from the Illinois Institute of Design, Chicago. There, he met another art student, Marilyn; they were married in 1956.

Three years later, the couple moved to Oak Park, where they raised four daughters and were very active in the community. They were members of Grace Episcopal Church for more than 35 years. 

After retiring in 1996, he and his wife retired to Columbus, Indiana, where he served on the board of directors of the Atterbury-Bakalar Air Museum. He also served as a docent at the air museum and helped restore vintage aircraft. In more recent years, the couple moved to Washington State to be closer to family. 

In addition to his wife, Glenn Leonhart is survived by his four daughters and their spouses, as well as 11 grandchildren and four great grandchildren; his brother, Don, and stepsister, Jane.

Services in Washington State are pending. Arrangements are being handled by Greenwood Memorial Park & Funeral Home, in Renton, Washington. Burial will take place at a later date in Mt. Emblem Cemetery, Elmhurst, Illinois. 

In lieu of flowers, donations may be made to Christ Episcopal Church, River Forest, or St. Paul’s Episcopal Church, Columbus, Indiana.
