Mack & Lincoln Hall founded the Hall-Mack music publishing house (later bought by the Rodeheaver Company). We speculate he may be Irvin H. Mack (1870–1950), buried in Northwood Cemetery, Philadelphia, Pennsylvania.
Mack’s works include:
- Boundless Love (Philadelphia, Pennsylvania: Hall-Mack, 1896)
- The Service of Praise, with Lincoln Hall et al. (Philadelphia, Pennsylvania: Hall-Mack, 1900)
- Gospel Service Songs, with George W. Sanville & Homer A. Rodeheaver (Rodeheaver, Hall-Mack, 1938)
