Houston Grand Opera (HGO), located in Houston, Texas, was founded in 1955 by German-born impresario Walter Herbert and Houstonians Elva Lobit, Edward Bing, and Charles Cockrell. HGO's inaugural season featured two performances of two operas, Salome (starring Brenda Lewis in the title role) and Madama Butterfly. David Gockley succeeded Walter Herbert as general director in 1972 and remained in the post until accepting the general directorship at San Francisco Opera in 2005. wikipedia
