Born in Munich, Germany, Moshammer had an education in retail industry trading. He began to design fashion in the 1960s.  His base of existence was his boutique “Carnaval de Venise” in Munich’s high society street, Maximilianstraße. There he created fashion for wealthy men from furs, cashmere, and silk. With this strategy he attracted the high society of Munich and Germany.  He had inherited the boutique from his mother, Else Moshammer. He had a strong relationship with her and frequently appeared in public with her. She died in 1993.  Moshammer was an eccentric and iridescent personality. He was well known for carrying his Yorkshire Terrier dog Daisy in public wherever he went, and even wrote a book about her.

Moshammer had a strong commitment to helping homeless people. For this he was awarded the “Martin’s Coat 2000” of the radio station, “Sankt Michaelsbund”.  Moshammer played in some made-for-TV movies like in the German crime series Tatort.  He collaborated with the musical band, “Münchner Zwietracht” (“The two garbs of Munich”), with whom he was a contestant in the German Eurovision Song Contest preliminary round show in 2001. The song was entitled “Teilt Freud und Leid” (“Share Happiness and Sorrow”).  In 2002, Moshammer sold a shirt thought to have been worn by Napoleon I at the Battle of Waterloo at auction for more than 62,000 euros ($81,200), donating the proceeds to a Munich homeless charity.

On the morning of January 14, 2005, at 9am, his chauffeur found him dead in his mansion in Grünwald, a suburb south of Munich. According to first reports of the public prosecutors, Moshammer had been strangled with a black telephone cable. The cable was found near the dead body. Daisy was found unharmed in the living room of his mansion.  The Munich police gave a press conference at noon on Sunday January 16, reporting that a 25 year-old Iraqi asylum seeker Herisch Ali Abdullah, who had been tracked down through a DNA database, had admitted murdering Moshammer. It has been alleged that Moshammer had refused to pay €2000 to the man, who was in financial difficulties, in return for sexual favors. Abdullah was sentenced to life in prison for the murder.
