Alexander Markowich Ostrowski (Ukrainian: Олександр Маркович Островський; Russian: Алекса́ндр Ма́ркович Остро́вский; 25 September 1893, in Kiev, Russian Empire – 20 November 1986, in Montagnola, Lugano, Switzerland) was a mathematician.
His father Mark having been a merchant, Alexander Ostrowski attended the Kiev College of Commerce, not a high school, and thus had an insufficient qualification to be admitted to university. However, his talent did not remain undetected: Ostrowski's mentor, Dmitry Grave, wrote to Landau and Hensel for help.
Subsequently, Ostrowski began to study mathematics at Marburg University under Hensel's supervision in 1912.
After World War I had ended Ostrowski moved on to Göttingen where he wrote his doctoral dissertation and was influenced by Hilbert, Klein and Landau.
In 1920, after having obtained his doctorate, Ostrowski moved to Hamburg where he worked as Hecke's assistant and finished his habilitation in 1922, becoming Professor of Mathematics at Basel.
