Helen Ling (née Yee Chow) is a former software engineer who worked at NASA's Jet Propulsion Laboratory (JPL).

[6] She made efforts to employ women computer programmers during the late 1950s and early 1960s - the programming group used to call themselves "Helen's Girls".

[6] Ling encouraged women to attend night school and obtain the correct qualifications to work alongside her at JPL.

[6] The author Nathalia Holt believes that "a lot of women ended up becoming computer scientists and engineers at JPL thanks to Helen's guidance".

[6] Ling developed software for many missions over the years, including the Infrared Astronomical Satellite, Magellan, Mars Observer and Topex/Poseidon.
