Biographical Note

The Richardson family was a prominent Cheyenne family. Originally the family began in the newspaper trade. After their arrival in Cheyenne in 1867-1868, the Richardsons established successful business ventures in Colorado, Wyoming, and Mexico. In addition, the family was active in social circles, the Episcopal Church, Masons, Shriners, and Knights of Pythias. With their wealth, they established a trust for the family and later established an educational endowment, and funded several noteworthy projects in the Cheyenne-Laramie area.

Warren Sr. became involved in the newspaper trade in town as editor of the Wyoming Daily Leader, a profession that a couple of his sons followed him into. He was also on the First National Bank board and the family was active in the Episcopal Church. Three additional children were born in Cheyenne: Valeria, Emil, and Arthur. Arthur died in 1900 at the age of 24. At the time, he was editor of the Cheyenne Sun newspaper and had just been elected to the state legislature.
