Frederick Trump (born Friedrich Trumpf; 14 March 1869 – 30 May 1918) was a German–American businessman and the patriarch of the Trump family. Born in Kallstadt, in the Kingdom of Bavaria (now in Rhineland-Palatinate, Germany), he emigrated to the United States at the age of 16 and started working as a barber. Several years later, in 1891, he moved to the Northwest. He made his fortune by operating restaurants and boarding houses (brothels) in Seattle and the mining town Monte Cristo, and brothels in the Klondike Gold Rush. He later returned to Kallstadt and married.
Bavarian authorities accused him of emigrating when he was young to avoid fulfilling his military service, so he lost his Bavarian citizenship; he and his family returned to the United States.
He worked as a barber and hotel manager, and began to acquire real estate in Queens. He was the father of Fred and John G. Trump, and grandfather of Donald Trump, the 45th president of the United States.
