Lorenz's operatic and recital career lasted almost three decades. He became known as one of the world's leading heldentenors, particularly renowned for his performances as Tristan.
At the height of his career in the 1930s and 1940s, Lorenz possessed a powerful, ringing, impassioned voice. Many of his recordings of operatic arias are now available online. Notably, he was recorded live in a performance of Die Meistersinger at the Bayreuth Festival (1943), under the baton of Furtwängler; and, in a performance of Götterdämmerung, also at Bayreuth (1952), under the baton of Josef Keilberth. He was also a notable Otello, Bacchus and Herod.
Personal life
Lorenz was homosexual, but from 1932 he was married to Charlotte (Lotte) Appel, who was Jewish and was aware of his homosexuality. His homosexuality was mostly tolerated by the Nazis as a well-known secret. When Lorenz had to appear in court because of an affair with a young man, Joseph Goebbels advised Winifred Wagner, the director of the Bayreuth Festival, that Lorenz would not be suitable for the Festival. Wagner answered that in that case she might as well close the Festival because, without Lorenz, "Bayreuth can't be done."[2]
As for his Jewish wife, Lorenz insisted on being open about his marriage, which was taken as a provocation by the Nazis. When Lorenz was away from home, the SS burst in and tried to arrest his wife and mother-in-law. At the last moment they were saved when Lotte Lorenz called the sister of Hermann Göring. The SS was ordered to leave their residence and not to bother the two women. Göring stated in a letter of 21 March 1943 that Lorenz was under his personal protection and that no action should be taken against him, his wife, or her mother.[2]
