The Mather Mansion as it is officially known was completed in 1910 by the famous New York-trained preeminent Cleveland architect Charles F. Schweinfurth who built the 45-room Tudor Revival style (which hearkens back to English country gentry) home for the illustrious Cleveland shipping and ore mining magnate Samuel Livingston Mather.

John D. Rockefeller, the undisputed king of Standard Oil and richest man in history it is alleged, Amasa Stone the Cleveland railroad baron father of Mather's wife, Charles F. Brush the inventor, George Worthington, Marcus A. Hanna, John Hay, Jeptha Wade, Charles E. J. Lang, and Mather all had homes built here by 1911.

A few still survive including Mather's, Case's near Case Western Reserve University in the University neighborhood, the Stager Beckwith near the Cleveland Clinic Main Campus, and the Parker-Hannifin House on the Cleveland State Campus which serves as the School of Graduate Studies at CSU.

[10] The Mathers also owned a summer residence named Shoreby in the Cleveland municipality Bratenahl, which still has the 6th highest per capita income at over $80,000 in the state of Ohio.

The survival of this homestead is a boon to Cleveland architectural historians and provides them a glimpse into early 20th century residential dwelling construction.

[13] Many of these homes therefore sported huge front lawns that needed to be meticulously manicured by staff or groundskeepers, their duties would include tending the many lavish gardens around the property.

The house cannot simply be approached from the street, it must be accessed by a plot of land that is controlled by the university and once had a long inclined driveway leading up from lower-leveled Euclid (please see photo).

[7] The mansion was most likely not a terribly happy place for Mather and his young family as his wife's death left a hole, and this may be why some have said the house seems spiritually unsettled.

[18] The current director of the OGH group, Peggy, led several people on guided tours of the 45-room manor to hunt for spirits and casually asked if any ghosts of the Mather family were present in various rooms, later claiming that she heard a child laughing which is interesting considering that youngest Mather (Philip) would have been over 15 by the time the family settled into the brand new abode.
