A single composite scan of two small documents Constantine kept together in his wallet: his Social Security card (issued at 2540 Cambreleng Avenue, the Bronx) and his first private-practice business card (44 West 77th Street, on the Upper West Side, with a TRAFALGAR exchange phone number — placing the card in the late 1940s / early 1950s).
The Social Security card
SOCIAL SECURITY (card number redacted from public display per privacy convention; preserved in the family archive)
Constantine L. Jeannopoulos 2540 Cambreleng Ave New York 58, NY
The card was issued at his Cambreleng Avenue Bronx residence — a building Constantine and Sophie occupied during his Bronx VA-Kingsbridge / NY Orthopedic residency years (1946-1949). The Cambreleng address also appears on his WWII separation record (separation address) and his Bronx County Certificate of Registration as Physician (May 3, 1946; archive item 0003) of May 1946.
The Social Security Number itself resolves a small puzzle on the separation paperwork: when Constantine was discharged from the Army at Fort Dix on March 20, 1946, his Social Security Number field on the WD AGO 53-55 form was filled in as “None” — he had not yet been issued an SSN. The SSN card here, issued at the same Cambreleng address that’s on the separation form, was obtained sometime in the months after March 1946, likely in preparation for his postwar private-practice billing and tax filings. His SSN is preserved in the family archive for any future US-federal-records inquiries (VA pension, Medicare, etc.).
The business card — 44 West 77th Street
C. L. JEANNOPOULOS, M.D. BY APPOINTMENT ONLY
44 WEST 77TH STREET NEW YORK 24, N.Y. TRAFALGAR 3-5228
Several details on the business card date it to circa 1949-50:
- New York 24 — the two-digit pre-ZIP-Code postal-zone notation used in NYC from 1943 to 1963. “New York 24” specifically denotes the Upper West Side / Central Park West postal area.
- TRAFALGAR 3-5228 — the TR exchange (digits 8-7-, with the modern equivalent 212-873-5228). The Trafalgar exchange covered the western Manhattan blocks between approximately 70th and 100th Streets. NYC phone exchanges were converted to numeric formats throughout the early 1960s; Trafalgar was specifically transitioned in 1962.
- “BY APPOINTMENT ONLY” — the language of a solo private practice, distinguishing Constantine’s UWS office from the institutional consulting and academic appointments he was simultaneously holding.
The 44 West 77th Street address is between Central Park West and Columbus Avenue, one block north of the American Museum of Natural History, on a brownstone block popular with mid-century medical practices. Constantine’s Columbia-Presbyterian Asst Attending appointment (1949-51) and his Chief of Orthopedic Surgery at the First Army HQ Hospital, Fort Jay appointment of the same period sat alongside this private-practice address. The Trafalgar exchange placed his after-hours patient calls right onto the same neighborhood phone network as Columbia-Presbyterian and the Roosevelt Hospital.

Provenance
The composite scan — both small documents reproduced on one image — was made in March 2010 as part of Peter Jeannopoulos’s family-archive scanning session (catalog item 0032). The two documents had been kept together physically in the family papers, likely in Constantine’s personal wallet at the time of his death in 1980.
