Thanks, Charlie. Also for the record, the obituary contained some factual errors that ought to be corrected for posterity.
Also some omissions that deserve to be noted.

Helen was born on January 10 (not 21), 1921
Riki Schneyer's given name is spelled Erika (not Ericka).
Helen's sister is Mona Wasow (not Masow).

The omissions are of the names of Helen's other family members, which were supplied to the Post but not included in the article. They are: granddaughter Renata Ament, brother Donald Cantor of Boston, and neices and nephews Michael Cantor, David Murie, Robin Murie, and Oliver Wasow.
