Simon Mikcs-Bán stands near the beginning of the remembered noble line: a leading figure of the Baksa kindred whose descendants would branch into several Hungarian families. Through this medieval world of service, kinship, and landholding, the Csapi family tradition begins to take shape.

László I de Csapi represents the family’s rise among the gentry of Upper Hungary. The Csapi name belongs here to a world of county leadership, noble obligation, and frontier responsibility, setting the stage for the later generations who served in the orbit of kings and emperors.

András Csapi received arms from King Sigismund in 1418 and is recorded in the armorial tradition as “Chapi alias von Schapp,” a member of the Order of the Dragon. That German-form name is an important bridge in the family tradition: Csapi becomes Chapi, Chapi becomes von Schapp, and the path toward Tschopp becomes historically plausible rather than merely phonetic.

László Csapi served in the court and chancery world of Emperor Sigismund, whose imperial path led through the great councils of Constance and Basel. Basel in 1433 - 1434 gives the family tradition its most important historical setting: a plausible moment when a Hungarian Csapi / Chapi connection could enter the Upper Rhine and Basel region.

By 1530, the Tschopp name is rooted in Basel-Landschaft. Liedertswil was also known in local speech as Tschoppenhof, a name traditionally linked to Durs Tschopp, the farm owner attested there. This is one of the strongest local anchors for the early Baselbieter Tschopp family.

Born in Hölstein and a citizen of Ziefen, Johann Jakob Tschopp became an engineer, entrepreneur, public servant, and Basel-Landschaft government councillor for public works. During his term, the Waldenburg and Birsig valley railways were built, linking the Baselbiet more strongly to the wider region.

Born in Hölstein and of Basel, Hans Tschopp carried a Basel legal education into national service. He served for more than two decades as a judge of the Swiss Federal Supreme Court and became its president in 1973 - 1974.

Joseph Anton Tschopp was born in Basel, worked his way into leadership at Roche, and became a major public figure in Basel-Landschaft. He served in the Landrat, in Münchenstein’s local government, and in the Swiss National Council from 1952 to 1975.

Born in Basel, Peter Tschopp became an economist, professor, university leader, and member of the Swiss National Council. His public life joined academic work with political commitments to Europe, social policy, and broader participation in Swiss civic life.

Born near Basel and trained at the University of Basel, Jürg Tschopp became one of Switzerland’s leading biomedical scientists. His work on cell death, innate immunity, and the inflammasome helped open new paths in the understanding of inflammation and disease.
