MAAS, JOSEPH (1847–1886), English tenor singer, was born at Dartford, and became a chorister in Rochester Cathedral. He went to study singing in Milan in 1869; in February 1871 he made his first success by taking Sims Reeves’s place at a concert in London. In 1878 he became principal tenor in Carl Rosa’s company, his beautiful voice and finished style more than compensating for his poor acting. He died in London on the 16th of January 1886.
