Inventor of MARC dies?

A few days ago I got this email from a nonlibrarian friend, which is strange in and of itself:

Yesterday's NYT (p.C3) reported the passing of the developer of
MARC records.

I feel I owe her so much.

Are we talking about the same MARC, as in MARC 21--MAchine Readable Cataloging?

Although I work with MARC every day, I'm no expert (I can't tell you why the 246 field dosen't end with a punctuation), I seem to recall that the MARC standard was arrived at via committee. Anyway, I googled "MARC inventor dies" and some other obvious searches, but I came up dry.

I must check the NY times for May 3, I suppose...
