Antoni Przybylski (1913 — 21 September 1985),[1][3] (Polish pronunciation [anˈtɔɲi pʂɨˈbɨlskʲi]), sometimes referred to as "Bill",[1] was a Polish-Australian astronomer best known for discovering the star that was named for him.

[2] At the outbreak of the Second World War, he joined the Polish Army and served as an artillery officer during the defense of Warsaw, after which he was taken prisoner and interned in Mecklenburg.

[1] In 1941, he escaped, and made his way across Germany, mostly at night, until he finally arrived in Switzerland, where he spent the rest of the war as a student and instructor at ETH Zurich.

[1] At ETH, he eventually earned a Doctorate in Technical Science, writing a thesis titled "Determination of Oxygen in Copper.

[5] There, he spent five months as a manual laborer[6] for the Postmaster General's Department[7] before coming to the attention of Richard Woolley,[2] who recruited him to work at Mount Stromlo Observatory (part of the then-nascent Australian National University).
