Jerzy Maria Weyman (Polish pronunciation: [ˈjɛʐɨ ˈveyman]; born April 29, 1955)[1] is a Polish-American mathematician whose field is algebra.

His maternal great-great-grandfather, Count Aleksander Fredro, was a poet and playwright from the era of Polish Romanticism, while his great-grandfather, Piotr Szembek, served as a military general in the 19th century.

Enrolling in the Faculty of Mathematics at Nicolaus Copernicus University of Toruń in 1973, Weyman developed a passion for algebra, particularly influenced by his mentor Tadeusz Józefiak.

Weyman returned to Poland in the early 1980s, continuing his role at the Mathematical Institute and collaborating on commutative algebra problems.

In 1982, he received the Award of the Polish Mathematical Society for Young Mathematicians, and in 1984, he became a laureate of the Kazimierz Kuratowski Prize along with Piotr Pragacz.
