Illichs

Illichs refers to people bearing the surname Illich. The surname is of Slavic origin, typically derived from the given name Ilija (a form of Elijah) with the patronymic suffix -ich, indicating descent or lineage. Variants and spellings occur across Central and Eastern Europe, and among diaspora communities in North America, where the name has been carried by immigrants and their descendants.

Notable bearers of the surname Illich include Ivan Illich (1926–2002), an Austrian-born priest, philosopher, and social critic. Illich is best known for challenging established institutions and the assumptions of modern industrial society. His influential works, such as Deschooling Society (1971) and Medical Nemesis (1974), critique education systems, medicine, and development narratives, and he remains a reference point in discussions of critiques of modernization.

In addition to Ivan Illich, other individuals with the surname have appeared in regional, academic, or professional contexts, though none have achieved the same international recognition as Ivan in widely cited reference works. The surname thus appears in genealogical and biographical contexts primarily through its association with Illich and related lineages.
