The Czech Pharmaceutical Museum in Kuks (a centre of Charles University in Prague – the Faculty of Pharmacy in Hradec Králové) has provided access to a volume containing German and Latin medical recipes by Guido Dihr from the second third of the 18th century. Its compiler joined the Order of the Brothers of Mercy in 1739; in the years 1757–1763, he was the prior of the monastery of this order in the Old Town of Prague. He died in 1772.
