We copy the sad news from Linn’s Stamp News website, published on 22nd March:
Sergio Sismondo, an esteemed postal historian and philatelic dealer whose encyclopedic knowledge of classic-era stamps and postal history enriched collectors from around the world, died March 13 in Syracuse, N.Y., at the age of 80.
Mr. Sismondo was born in Italy and during the course of his life became fluent in five languages: Italian, French, Portuguese, Spanish and English.
Mr. Sismondo, widely regarded as an expertizer, stamp dealer and author, was profiled in “Linn’s Most Influential Philatelists and Their Epic Stamp Stories”, published in 2022.
Linn’s obituary goes on describing how Sergio Sismondo was heavily influenced by Victor Kneitschel, how he handled some of the world’s greatest rarities, his systematic approach to the expertisation process and his contribution to Scott Classic Specialized Catalogue.
