[1] Andrzejowski was born the son of a bank clerk and property manager in the village of Varkovychi [uk] in the present-day Rivne Oblast in Ukraine.

Andrzejowski was a student of the botanists Franz Scheidt and Wilibald Swibert Joseph Gottlieb von Besser in Kremenets.

After his Polish-language lyceum was dissolved in 1832, he was an assistant to Wilibald Swibert Joseph Gottlieb von Besser and lecturer at Kiev University beginning in 1832.

In 1825 he published a list of Ukrainian wild plants and posthumously in 1869 a flora of Ukraine and its neighboring areas.

Species first described by Andrzejowski include small-flowered winter-cress (Barbarea stricta) in the crucifer family (Brassicaceae).
