Robert L. S. McClure (1888-1949) was born in New York, New York, and died in Valhalla, New York. He was the son of Samuel Sidney McClure, 1857-1949, founder and publisher of McClure's Magazine. He was also the godson of, and was named after, the author Robert Louis Stevenson, 1850-1894, who was a personal friend of his father's and whose work was syndicated in McClure's. Robert L. S. McClure was an investment banker and real estate agent. He married Edith McClure (b. Dodds) in London, England, in 1909, and they settled in Yonkers, New York, moving to Scarborough, New York, sometime before 1924. McClure served as a first lieutenant in the U.S. Army Air Service in World War I. He went on to become the vice president and director of J. G. White & Co. He moved to New Rochelle, New York, in about 1934 and to Mamaroneck, New York, in about 1948. In May 1906, McClure confirmed to Mary Baker Eddy's student Alfred Farlow that McClure's intended to print a lengthy and controversial article about Eddy written by Georgine Milmine, which it did in serial format from December 1906 to June 1908.
