Xavier Galezowski (1832–1907) was a Polish ophthalmologist practicing in France who was one of the first clinical practitioners of his specialty.

[1] Galezowski was born as Ksawery Gałęzowski in Lipowiec, Poland (after partitions part of the Russian Empire), to Franciszek and Antonina née Szokalska.

He earned a degree in medicine from the University of St. Petersburg in 1858 and received a gold medal for his thesis on the ophthalmoscope.

As one of the first private practitioners of his specialty, and due to his skill, Gazelowski's public reputation grew and his clinic treated an average of 8800 patients per year.

[4] Among his patients was Paul Lafargue, who spoke admiringly of Galezowski's work in a letter to Friedrich Engels, who also suffered from tear duct problems, dated July 28, 1887.
