Judith Lynn Pipher (née Bancroft, June 18, 1940 – February 21, 2022) was a Canadian-born American astrophysicist and observational astronomer. She was Professor Emerita of Astronomy at the University of Rochester and directed the C. E. K. Mees Observatory from 1979 to 1994. She made important contributions to the development of infrared detector arrays in space telescopes.

Early life and education

Judith Lynn Bancroft was born on June 18, 1940, in Toronto, Ontario, to Earl Lester Alexander Bancroft and Agnes May Kathleen (née McGowan) Bancroft.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american astrophysicist and observational astronomer. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q15511666. VIAF identifies the subject as 18712590. The Library of Congress control number is n86803494. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1940, 2022, 1979 and 1994.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
