In 1994, Seel published the book "Moi, Pierre Seel, déporté homosexuel" ("I, Pierre Seel, Deported Homosexual"), written with the assistance of journalist and activist Jean Le Bitoux, founder of the long-running French gay periodical "Gai Pied"; the book subsequently appeared in translation in English, German, Spanish and Danish. Seel appeared on national television and in the national press in France. In June 1996, shortly before his autobiography appeared in German translation, Austria was the first German-speaking country he visited since World War II. He felt it important to visit the Austrian concentration camp site at Mauthausen with its memorial to homosexuals persecuted by the Nazi regime, the first of its kind worldwide when it was dedicated in 1984. He also paid his respects to Josef Kohout by visiting his grave in Vienna's Baumgartner Cemetery. In 1997, Seel spoke at the dedication of the memorial to homosexuals persecuted by the Nazi regime at Berlin's Nollendorfplatz.
