Dr. Bullitt’s Home (1925) In August 1925, following the death of homeowner Florence Smith and the subsequent Land Court trial, John C. Bullitt Jr. and his wife Edna D. Bullitt of Wayne, Penn., claimed the title to this property.
Dr. John Christian Bullitt, 2d (1871–1925) used this house as a summer home. He was the son of prominent Philadelphia lawyer, banker, and railroad tycoon John C. Bullitt and his wife Therese Langhorne. Dr. Bullitt was born in Philadelphia, graduated from the University of Pennsylvania, and received his medical degree from the Pennsylvania Medical School. He practiced medicine for many years in Philadelphia. The 1910 census of the Norwood, Penn. lists him as a 38-year-old divorced physician boarding with a family there, and in 1911 he married Edna Deaver. In 1918 they began summering on the Vineyard.
He died in October 1925, only a few months after obtaining the house, at the age of 52 in Vineyard Haven. He is buried in Wayne, Penn. His obituary notes that “He had taken great interest in remodeling the old Capt. Lorenzo Smith house, which he purchased some time ago, and which he intended for his own use. The house is nearly complete….”
