William Welsh Harrison

In 1903, their houseman robbed Bertha of $17,000 worth of jewels from their Glenside home while the family was eating Thanksgiving dinner.

[17] In 1881, 31-year-old Harrison purchased Rosedale Hall Glenside, Pennsylvania, from J. Thomas Audenreid and expanded the estate to 138 acres by 1891.

[18] In 1893, Rosedale Hall burned to the ground and Harrison again hired Trumbauer, in what is considered his first major commission, to build a new home on the site.

Trumbauer designed an imposing 40-room mansion, inspired by Alnwick Castle, the medieval seat of the Dukes of Northumberland.

After his death in 1927, his widow sold Grey Towers in 1929 to Beaver College (now Arcadia University), for $712,500 equal to $12,642,733 today.
