Charles Leroy "Chuck" Schaden, born June 29, 1934, is a Chicago-area broadcaster and historian who hosted the program Those Were the Days on local radio from 1970 to 2009. Schaden plays recordings of classic old-time radio shows and reminisces with radio personalities about the early days of broadcasting. The program first aired on WLTD in Evanston in 1970 and then moved to WNIB, Classical 97 in Chicago from 1975 to 2001, and since 2001 it has been heard on WDCB 90.9 FM, a public radio station in Glen Ellyn, Illinois.

Born in Chicago, Schaden is a former newspaper editor and marketing executive who turned his hobby of collecting radio shows into a vocation. For his efforts in preserving and documenting radio history he was inducted into the National Radio Hall of Fame in 1993, the first radio fan to receive this honor. He has often served as a consultant on topics related to broadcasting history, and he is a founding member of the Board of Directors of Chicago’s Museum of Broadcast Communications.
