Johan was a historian. Heauthored the “Chronicle of Seedorf” which was a history, known to have been written in Latin, about a monastery to St. Lazarus that was located in a town called Seedorf, in the Canton of Uri, Switzerland. Johan’s chronicle was finished in 1360, meaning Johan lived until at least this year.
Johan’s chronicle was destroyed in a fire in 1590. Before his chronicle was destroyed, however, other historians had made references to it. A 1566 history of the same monastery relied heavily upon Johan’s work. In the 1700s a forgery of Johann’s work was created but it has no connection to the lost original.
While sources agree that Johan was the son of Burkhard Zumbrunnen, I believe this is some confusion in these sources and that he is the son of Burkhard Zumbrunnen who was a Knight in the Order of St. Lazarus, and the grandson (not the son) of Landammann Burkhard “Schüpfer” Zumbrunnen. Most sources agree that Johan was the father of Walter Zumbrunnen, although one source: the Nobiliaire Militaire Suisse, says that Johan’s brother Heinrich was the father of Walter Zumbrunnen. Other sources agree that Heinrich was the uncle of Walter.
