The American Philatelic Society announced the induction of Clark, Lievsay, Saadi, Winter and Ohlman into its Hall of Fame. The honour recognises deceased philatelists whose work made a lasting contribution to the hobby.

Their activities span collecting, research, exhibiting, dealing and institutional service. Historical auction catalogues and specialist publications associated with such figures can remain important references long after the original sales or studies.

Biographical recognition helps collectors trace the people behind catalogues, collections and organisations. Any detailed claims about an inductee should be tied to the APS citation rather than repeated from unsupported collector lore.
