A DOOR TO DISCOVERY: Gary Felsenfeld (1929–2024), scientist emeritus in NIDDK’s Laboratory of Molecular Biology, displayed correspondence he received throughout his 62-year NIH career on his office door. Each instance features some misspelling of his name. It was also a doorway into his sense of humor.

Felsenfeld classified the misspellings into point mutations, frameshift mutations, insertions, deletions, and translocations. The door originated in Building 2, home to Felsenfeld’s first NIH lab; when he moved to Building 5 in the 1990s, he was allowed to take the door with him.
