Nan Dieter-Conklin (1926 – November 16, 2014), also known as Nannielou Reier Hepburn Dieter Conklin, was an American radio astronomer.

[1][2] She attended Goucher College[3] to study mathematics, but an astronomy course taught by Helen Dodson sparked her interest in that subject.

Dieter spent summer internships at the Maria Mitchell Observatory, working under Margaret Harwood.

[12][13] During her graduate work in Massachusetts, she was on the staff of the Air Force Cambridge Research Laboratories at Hanscom Field.

Stemming from an unstable family background, she found solace and security in the predictability of the physical sciences amidst the complexities of human relationships.

In an era where women constituted only 3% of physicists and astronomers, facing both overt and covert discrimination, Conklin drew inspiration and resilience from role models like Helen Dodson and Cecilia Payne-Gaposchkin.
