Henry L. Spann (February 13, 1879 – October 3, 1946)[1][2] was a church and theater architect in Buffalo, New York.[3] He is credited with designing about a dozen of the city's theaters as well as ones in surrounding areas including Niagara, New York.[4] He built theaters for various owners.[5] He worked with his much younger brother William T. Spann who was also an architect.[6] Spann also designed buildings for Catholic institutions in the area.
Spann's theater designs for Michael Shea incorporated commercial space.[7]
The North Park Theatre he designed remains in existence and efforts were underway to preserve the Sattler Theater on Broadway.[8] Shea's Seneca commercial building section remains and was being proposed for National Register of Historic Places consideration in 2018.[9]
