Mary Brennan lives in Santa Fe, New Mexico. She and her husband, Curtiss, moved next door to Dorothy McKibbin, the “Gatekeeper to Los Alamos.”

Brennan has fond memories of Dorothy, who ran the Santa Fe office at 109 East Palace for the Los Alamos National Laboratory. McKibbin hosted many project workers at her house for various social events, including thirty weddings.

The Brennans are the current owners of McKibbin’s house and still reside next door.
