5010 Montrose Blvd. – Houston TX (built 1923; demolished 1970)
The building was originally the home of Neill Turner Masterson, son of Harris Masterson I and father of Harris Masterson III. The Masterson family only lived there until about 1925 and it became home to the Sterling Mutual Life Insurance Company.
Beginning in 1949, Hedgecroft Hospital was located on Montrose Blvd. at the current site of the Museum of Fine Arts Houston Administration Building. The Hospital, opened in 1942, was run by Nell H. Stone and underwent a 10,000 square foot modern expansion in 1952 to house polio patients (as seen below, from Houston Magazine). Later it became a mental institution and then was torn down in 1970.
Here is a 1923/1924 picture of the Masterson house from Houston Public Library:
