Frederick Werlé (1910-1997) was a composer, music teacher, and a former dean of the Mannes College of Music. His papers primarily consist of reel-to-reel and LP audio recordings and original music manuscripts. Also present in the collection are newspaper clippings, published music scores, concert programs, correspondence and notes.

This collection consists of transcripts of seventeen interviews with Esther Hoffman Wexler (1918-2014), conducted by her cousin, Lawrence Freund, between 2012 and 2014. Hoffman, a Canadian-born concert pianist and a longtime piano teacher at the Mannes College of Music (which became a division of The New School in 1989), discusses her life experiences and her career as a musician and as a teacher in New York City and Toronto.
