Irving P. Andrews (1925 - 1998) was a prominent attorney in Denver, Colorado. After serving as a Ensign in the U.S. Navy becoming the first Black graduate of both Colorado College and DU Law school, he had a career spanning over four decades. He argued many cases in Denver City and County and served on the Brown v Board of Education legal team. This house served as both his residence and office from the 1970s onward. Despite his reputation as an exceptional attorney, most office buildings would still not rent space to him in downtown Denver. He purchased the duplex at 2241 York Street in the 1970s, using the downstairs as his residence and upstairs as his law office.
