Houston Grand Opera (HGO) is an American opera company located in Houston, Texas. Founded in 1955 by German-born impresario Walter Herbert and three local Houstonians,[1] the company is resident at the Wortham Theater Center. This theatre is also home to the Houston Ballet. In its history, the company has received a Tony Award, two Grammy Awards, and three Emmy Awards, the only opera company in the world to win these three honours. Houston Grand Opera is supported by an active auxiliary organization, the Houston Grand Opera Guild, established in October 1955.[2]
