According to Larry Warren in "Lester Horton, Modern Dance Pioneer", ©1977 by Marcel Dekker, Inc., New York, N.Y.:
"... When Iredell, whose fortunes continued to decline, decided to move back to Brazil, Indiana once again, Lester made a decision of his own. He would stay in Indianapolis. Earning enough money from various part-time jobs to be on his own, he was somehow able to scrape together the money for a few lessons from the renowned ballet master Adolph Bolm in Chicago, 175 miles away. But this training period was not destined to last beyond lesson number two, for Bolm, who had startled Paris in 1909 with his magnificent dancing in the Diaghilev Ballet, was a strict task master. Lester liked Russian Ballet training no more than the Italian version he had resisted in Mlle. Hewe's studio. One final attempt in the mid-twenties to study ballet, this time at the Pavley-Oukrainsky School, also in Chicago, had similar results. Nevertheless, Horton remembered these old maestros fondly and always spoke highly of Bolm years later when both of them were teaching in Los Angeles. When he started teaching on his own some years later, the difficulty of his classes made the ones he avoided seem tame."
Some of Adolph Bolm's students also studied with Lester Horton:
