I have found no information about Conrad’s life aside from the following story:
In 1628, the plague struck Fribourg, and over 30 of the college students died. Classes were suspended for six months, and most students returned home. Conrad, apparently in his fourth year at the school, was prevented from leaving by his hostess, Ursula Burgknecht, because of unpaid debts to her. Apparently, the dean of the school intervened to negotiate the boy’s release. Conrad’s father later filed some sort of grievance with the city over the incident with the hostess. The story is recorded as this combination of pestilence and the bad hostess kept the Zumbrunnen and many other boys from Uri away from the school for several decades.
