Lars Ulrich

Metallica drummer Lars Ulrich grandfather was 28-time tennis champion

Lars Ulrich  is a Danish-American drummer and one of the founding members of American heavy metal band Metallica. He was born in Gentofte, Denmark to an upper-middle-class family. A tennis player in his youth (he is the son of former tennis pro Torben Ulrich), Ulrich moved to Los Angeles, California at age sixteen in the summer of 1980 to pursue his training; though rather than playing tennis, he began playing the drums. After publishing an advertisement in a local Los Angeles newspaper called The Recycler, Ulrich met James Hetfield and formed Metallica.

his grandfather Einer Ulrich competed in the 1926 Wimbledon Championships and reached the fourth round in the singles event in which he lost to Jean Borotra. In the doubles and mixed doubles event he was eliminated in the second round. His second and final participation was at the 1929 Wimbledon Championships in which he reached the second round in all three events. He was a 28-times national champion of Denmark, five of which were consecutive singles victories. He played for the Davis Cup 74 times.
