Harry Lehrer (October 15, 1904 – June 26, 1972) was an American licensed pharmacist, physician, and real estate speculator[1] who owned the Bumiller Building in Los Angeles.

Working as a stenographer for a wholesale grocery company, Lehrer took a California pharmacy board review course at night and was certified by examination as a pharmacist in 1924.

Lehrer was unable to obtain financing to buy one additional building, a former Thrifty Drug Store, 133-135 South Broadway; its owner was Gabriel Laskin.

[10] Lehrer bought the Bumiller Building from the estate of Lillian E. Schramm in 1958,[11] and had his medical offices on the ground floor until his death in 1972.

[12] Built in 1906,[13] the Bumiller Building, designed by the architects Morgan & Walls,[14] was constructed of reinforced concrete in Renaissance Revival style.
