Maria Jeritza — Italian Musician born on October 06, 1887, died on July 10, 1982

Maria Jeritza was a celebrated Czech soprano singer, long associated with the Vienna State Opera and the Metropolitan Opera. Her sensational rise to fame and spectacular beauty and personality earned her the nickname "The Moravian Thunderbolt"... (wikipedia)

It is hard to describe the thrill of creative joy which the artist feels when the conviction seizes her that at last she has caught the very soul of the character she wishes to portray, in the music and action which reveal it.
The real exertion in the case of an opera singer lies not so much in her singing as in her acting of a role, for nearly every modern opera makes great dramatic and physical demands.
