home. Lyndhurst, completed in 1889 and demolished around 1942, was located at 1165 Beechwood Boulevard in the Squirrel Hill neighborhood of Pittsburgh. Thaw died in Paris on August 17, 1889. Legacy He is considered to have been one of the 100 wealthiest Americans, having left an enormous fortune. He was the father of Harry Kendall Thaw, whose 1906 killing of noted architect Stanford White resulted in a sensational "trial of the century" and aftermath. A small town in East Central Illinois is named Thawville in honor of William Thaw Sr. William K. Thaw owned a controlling interest in the GCS and Thawville was platted in November 1871. The GCS went into receivership during the panic of 1873 and was later taken over by the Illinois Central Company. William K. Thaw visited the town only once—in February 1874 or 1875. At that time he was snowbound in town for two or three days. Taylor John owned the land now included in Thawville as far east as Wood St. and as far north as County Road (State Aid Road). Although an attempt to incorporate Thawville failed in 1897, another attempt was successful in 1903. The town is still there. A plaque is on the front 304 Wood Street in Downtown Pittsburgh, commemorating his birthplace. References External links Biography of William Thaw Historic Pittsburgh Guide to Thaw, William.
