Oh, What a Beautiful Mornin' was written about this property.

The obituary of Gerald C. Sapperstein was in the Philadelphia Inquirer, 6/8/12, at B6, and read in part: Mr. Sapperstein was a partner in R&G Properties, which his family said developed the office complex known as the Farm, on a Doylestown Field that inspired Oscar Hammerstein II to write the lyrics for Oh, What a Beautiful Mornin' for the Broadway musical Oklahoma! Hammerstein lived across a road from the field. See the entry for Highland Farm on Cyber Plaque.
