Ľudmila Pajdušáková (29 June 1916 – 6 October 1979) was a Slovak astronomer.
She specialized in solar astronomy, and also discovered a number of comets, including periodic comet 45P/Honda-Mrkos-Pajdušáková,[1] and the non-periodic C/1946 K1 (Pajdušáková-Rotbart-Weber), C/1948 E1 (Pajdušáková-Mrkos), C/1951 C1 (Pajdušáková) and C/1953 X1 (Pajdušáková).
She observed at Skalnaté Pleso Observatory and became its third director from 1958 to 1979.
[2] In a 1951 "Comet Notes" article in Publications of the Astronomical Society of the Pacific [PASP 63 (1951) 209], Leland E. Cunningham in discussing comet C/1951 C1 refers to her as "Miss Pajdušáková (Mrs. Mrkos)", and there was an astronomy book published in 1956 by Ľudmila Mrkosová-Pajdušáková, as well as various scientific papers under this name from approximately 1952–1958.
However, their respective biographies do not seem to mention any such marriage which, after all, ended in a divorce.
