Jean Winkler

Jean Winkler was a Swiss philatelist who was added to the Roll of [Distinguished Philatelists] in 1971. One of the first collectors to interest himself in Swiss Prephilately he belonged to the small group of first-generation pioneers in this then very exotic field of collectiong covers without stamps. His first work on the subject, "Les Marques Postales de la Suisse 1695-1850" played an important role in firmly establishing the rich field of prephilately in the Swiss philatelic landscape. His subsequent revised and extended book "Handbuch der Vorphilatelie" remains the definitive reference work on Swiss prephilately to this day.
