Robert August Holekamp (May 4, 1848 – May 1, 1922) was a businessman and apiarist from the St. Louis suburb of Webster Groves, Missouri.

In early 1885, Holekamp bought Gray's ownership interest and in December of that year he sold the company to Charles H. Huttig for $40,000.

[5] As a result of the coal pollution in St. Louis and following his doctor's advice, in 1896 Holekamp moved to a farm located three miles outside of Annapolis in Iron County, Missouri.

In addition to the wholesale and retail sale of lumber and hardware, the firm was active in real estate development.

Holekamp and his sons established many of the subdivisions and built many of the homes in Webster Groves, in neighboring Kirkwood, and in the surrounding southwestern suburbs of St. Louis.

[9] While living in rural Annapolis, Missouri, Holekamp developed an interest in apiology and began beekeeping.
