Businessman Harry Whitney Treat arrived in Seattle from New York around 1904. He bought hundreds of acres of land north of Ballard where he developed the Loyal Heights area and Golden Gardens Park. The Treats owned a mansion on Queen Anne Hill, a large country estate in Loyal Heights, and were active in Seattle society. Treat was an avid horseman who was particularly known for his skill in handling horse teams. He named two new developments Loyal Heights and Loyal Beach (later known as Golden Gardens), as well as his trolley line the Loyal Heights Railway after his youngest daughter Loyal Graef Treat.

This photo is marked as a copy in a collection from McBride and Anderson photographers. Born in 1863, Ella McBride began working in the photography field in 1909 when she managed the Edward Curtis Studio. She opened her own studio in 1917 with Wayne Albee. Albee moved to San Diego in 1925, and McBride continued to operate a studio in various Seattle locations. In 1932 she partnered with Richard Anderson; they continued to work together until she retired in 1954 due to her failing eyesight. She died in 1965 at the age of 102. Taken before the McBride-Anderson partnership began; it is not known which partner was the photographer or if the original photograph was taken by another photographer.
