Martin Erler

Martin Erler (c. 1920[1] – 11 August 2014[2]) was a German philatelist who was an expert on the revenue stamps of Germany who with John A. Norton (died June 1980[3]) wrote the only comprehensive catalogue of German revenue stamps.

The first volumes of the Erler catalogue were based mainly on the author's own collections and a 1961 work by John Norton.

Erler was a member of the Royal Philatelic Society London (RPSL) since 1990 and was made a Fellow in 1992.

[5] In April 1991, Erler gave a display to the RPSL on the Revenue Stamped Papers in the Wurzburg Area of Northern Bavaria during Napoleonic Times, which was described by Clive Akerman as including material of the "utmost rarity".

[6] Erler has been credited with being one of the individuals who was instrumental in having revenue philately accepted as a distinct competitive class in its own right by the Fédération Internationale de Philatélie.
