She was elected as a Fellow of the [[American Association for the Advancement of Science]] in 1957. At that time she was also affiliated with the [[Ballistic Research Laboratory]].<ref>{{Cite web |url=https://www.aaas.org/fellows/historic?field_last_name_value=H&name_combine=&field_institutional_affiliation_value=&field_address_city=All&field_address_when_elected_administrative_area=All&field_address_when_elected_country_code=All&field_year_elected=&field_primary_aaas_section=All&field_status_value=All&field_year_status_changed_value=&page=43 |title=Historic Fellows; American Association for the Advancement of Science |date=April 19, 2022 |website= |archive-url=https://web.archive.org/web/20220419031935/https://www.aaas.org/fellows/historic?field_last_name_value=H&name_combine=&field_institutional_affiliation_value=&field_address_city=All&field_address_when_elected_administrative_area=All&field_address_when_elected_country_code=All&field_year_elected=&field_primary_aaas_section=All&field_status_value=All&field_year_status_changed_value=&page=43 |archive-date=19 April 2022 |url-status=dead}}</ref>
