Doug Christensen was one of the DuPage Theatre's strongest advocates. He was instrumental in getting the theatre listed on the National Register of Historic Places and cared for her as no other. He made sure the theatre was clean, secure, and made many of the repairs needed during its time of neglect by the Village of Lombard. Doug had the spirit of the DuPage Theatre in his soul.

Doug Christensen knew the DuPage Theatre intimately. He was so familiar with the grand lady that he mesmerized visitors with his accounts of the theatre's history. Doug's passion for the theatre's restoration was evident to all who heard him speak.

Attempts at restoring, preserving, and saving the DuPage Theatre from destruction, was not the first of Doug's involvement with historical preservation. Shortly after graduating from high school, Doug and four other young men took it upon themselves to preserve historical artifacts from the early days of railroad. Their efforts resulted in the founding of the Railway Investment Club in August of 1959. Today this museum is The Fox River Trolley Museum located in South Elgin, IL.

Doug's involvement with establishing the trolley museum should not be a surprise to those who new him. In high school he was the vice president, then president of the Railroad Club. His eloquence at speaking and ability to write grew out of activities with the Quill & Scroll, Masque & Gavel, participation in Speech Contests, and managing advertisements in the school paper. In addition, Doug was a member in the Latin Club and Science Club (Glenbard West Pinnacle 1957).
