The Austrian landowner and researcher Ludwig von Comini, Edler von Sonnenfels (1814-1869) studied at the kuk forest school in Mariabrunn near Wien
. He then worked for the State Forestry Service in Tyrol for a few years. In 1849 he inherited wineries in Bolzano-South Tyrol. Here he first discovered the infestation with real in one of his vineyards in 1851 mildew
on some vines. He immediately started trying to fight this vine disease. When this mushroom appeared in almost all European wine-growing countries from around 1855, Comini traveled to Italy, France and Greece to find out about suitable repellents. Returning without result, through further attempts in 1865 he realized that dusting with powdered, dry sulfur
brought the desired success. Perhaps others have already come to the same conclusion. It is therefore no longer possible to clarify who can actually be considered the actual “inventor”. In any case, Comini spread his knowledge, spoken and written, in all Austrian winegrowing areas at the time, which earned him the nickname "Sulfur Apostle".
