Leroy N. "Lee" Clausen

Leroy “Lee” N. Clausen, age 77, of St. Charles, IL passed away peacefully on Monday, December 22, 2025, with his loving family by his side. 

Lee was born on May 31, 1948, in Chicago IL, the son of Norman and Amelia (Gadwill) Clausen.

Lee dedicated his life to his family and a 34 year teaching career at Lincoln Elementary School in Elmhurst, IL. Lee shared his love of the outdoors and science with his students through many special programs including Outdoor Ed, Starlab and building and maintaining the prairie garden. He was passionate about teaching outside of the classroom and provided amazing opportunities for his students through the Silverado Project where he was recognized for collaboration between education and business. 

Lee’s greatest joy in life was spending time with his family. He provided a beautiful childhood for his children through many adventures like camping, fishing and trips to Galena. He also enjoyed all the time he spent with his grandchildren supporting them and their many interests.

His gentle nature, patience and humor made him an exceptional husband, father, grandfather and teacher. Lee’s dedication to his family built a lasting legacy of love and tradition that will live with his family forever. 

Lee is survived by his wife of 55 years Mary (O’Connor); children Christopher (Rachel) of Pingree Grove, Beth of St. Charles, Emily of Batavia, Sara (Jeff) Kramer of Pingree Grove and Amy of Aurora; grandchildren Josiah, Michael, Isaiah, Aidan, Mariana, Amelia, Jaden, Matthew, Kaitlyn and Avery; siblings Lorraine Gordon of Maryland, Edward of Elgin, many dear nieces, nephews and other dear relatives and friends.
