Ira Diamond Gerald Cassidy
Gerald Cassidy was raised in Cincinnati, Ohio, and studied there at the Art Institute under Frank Duveneck, who had also mentored Joseph Sharp and Walter Ufer.
In 1898, while working as a commercial artist in New York City, Cassidy contracted Tuberculosis and was sent to a sanitarium in Albuquerque, New Mexico. As his health improved, Cassidy found that he preferred the New Mexico landscape and people to New York. He began to paint the local Indians, including the Navajo Chief Vicente.
After his recovery, Cassidy moved to Denver, where he worked as a lithographer. In 1912 Cassidy married Ina Sizer Davis, the sculptor, and two years later they moved permanently to Santa Fe, where Cassidy abandoned commercial illustration and concentrated on painting.
His reputation as a painter was established in 1915 when he was awarded the grand prize and gold medal at the Panama-Pacific Exposition in San Diego, California for a series of murals for the Indian Arts Building, which depicted the life of the Southwestern Indians.
