Abe Dudnik worked three sales jobs while attending night school at John Marshall School of Law. Known as a fearsome trial lawyer, he specialized in personal injury cases and founded the A.H. Dudnik Law Firm, which later became Nurenberg, Plevin (now Paris), Heller & McCarthy. He was regarded as a pioneer in jury trial techniques and specialized in representing injured railroad workers when Northeast Ohio was a hub for the movement of cargo by train—successfully carrying the “Bug Bite” verdict up to the Supreme Court. A 1956 issue of the Cleveland-Marshall Law Review includes a dedication to Dudnik that notes that of the many high legal honors he had achieved, the one that pleased him most was his appointment as a member of the faculty of his law school.
