Frederic Chapin (1 December 1873 – 27 December 1947) was the composer who wrote the music for L. Frank Baum's 1905 stage musical The Woggle-Bug. Chapin was recommended for the job by Henry Raeder, the Chicago theatrical producer who staged the show. (Chapin's music for the show was generally praised by the critics, who treated Baum's scenario much more harshly.) Apart from this one connection with Baum and Oz, Chapin composed music for a number of shows in his era, including: Born in Cleveland, Ohio, Chapin died in Los Angeles.
