Wilhelmina Iwanowska (2 September 1905 â 16 May 1999) was a Polish astronomer and the first astrophysics professor in Poland. She was pioneer of astrophysics in Poland.
Iwanowska was born to a modest family of noble descent on the borderlands of Poland.
Wilhelmina Iwanowska began her studies at the University of Stefan Batory (USB) in mathematics. She began working at the university in 1927, studying under Juliusz Rudnicki. She earned her master's degree in analytic functions in 1929. Then, in 1933, she received her D.Sc. (Doctor of Science) in astronomy. By 1937, Iwanowska received her Docent degree in astronomy.
Iwanowska's astronomical career during her studies at the university. In 1926, Iwanowska was approached by Wà Âadysà Âaw Dziewulski, a professor at the university. Dziewulski offered Iwanowska a job at the Astronomical Observatory of the Jagiellonian University. By 1927, her profession as an astronomer had begun, a time period which included the rise of astrophysics in Polish science and its early accomplishments. From 1934 to 1935, she focused on astronomical spectroscopy during her internship at the Stockholm Observatory. In 1937, at the University of Stefan Batory, she presented her post-doctoral dissertation where "she characterized stellar supergiants based on the analysis of their spectral features."
From 1945 to 1999, Iwanowska worked at the university in Toruà Â. On 14 July 1945, she and some 200 other staff members from USB were transferred to Toruà Â. Iwanowska and the other scientists were successful in establishing a university in Toruà Â. On 26 August 1945, the Nicolaus Copernicus University was founded which included two departments, astronomy and astrophysics. She was one of the founders of the Nicolaus Copernicus University and the Toruà  School of Astronomy and Radioastronomy and helped develop many of their programs. In 1946, she became the first astrophysics professor in Poland.
Iwanowska was the head of the observatory in Toruà  from 1952 to 1976, which was the year of her retirement. Under her management, Dr. Iwanowska promoted nineteen doctors. Additionally, eight of her students went on to become professors. She was a frequent visitor of many observatories across Europe. She visited the United States and Canada. In January 1973, she was an honored guest of the Canadian National Nicolaus Copernicus Quincentenary Committee, the Royal Astronomical Society of Canada, and the National Research Council.
Wilhelmina Iwanowska died on 16 May 1999, aged 93. She was buried in Toruà  beside her mother, sister, and niece.
