In 1867 the Beardsley family moved to Champaign, Illinois, where Henry's father was a successful real estate broker and manufacturer.
Henry Beardsley moved to Kansas City, Missouri, in October 1886 where he worked for Jarvis & Conklin Mortgage Trust Company briefly before establishing a law practice the following year with Alfred Gregory, an old friend from Illinois.
