William Matheus Sullivan

Sullivan was also an art collector and he owned The Holy Family, by Anthony van Dyck, that hung in the carriage house after it became his playhouse; the painting is now at the Kunsthistorisches Museum in Vienna.

The visiting singers included the soprano Lily Pons, the tenor Edward Johnson, Grace Moore, Lawrence Tibbett and Geraldine Farrar.

[1] Sullivan is buried in Woodlawn Cemetery (Bronx, New York) with his partner, interior decorator Aaron "Arcie" Lubetkin (August 27, 1887 - September 1955).

At the death of Lubetkin and then Hoenig, the fund was turned over to form the "William Matheus Sullivan Musical Foundation".

"[5] The William Matheus Sullivan Musical Foundation is a non-profit organization dedicated to finding, developing, and furthering the careers of promising opera singers within the United States.
