Pamela Jane Hinchman and Ted DeDee are to be married Sept. 8 at the Four Seasons Hotel in Chicago. Justice Ruth Bader Ginsburg is to officiate.

Ms. Hinchman, 64, is an opera singer and professor of voice at Northwestern. She graduated from Cleveland Institute of Music and received a master’s degree in music from Curtis Institute of Music in Philadelphia. She is the daughter of the late Isabel Hinchman and the late Bruce Hinchman, who lived in Erie, Pa.

Mr. DeDee, 69, is the president and chief executive of La Jolla Music Society, an arts presenting organization. He graduated from the State University of New York at Fredonia. He is the son of the late Gladys M. DeDee and the late Edward D. DeDee, who lived in Rochester.

The bride’s two previous marriages ended in divorce. The groom was a widower.

The couple met in October 2015 at the Overture Center for the Arts in Madison, Wis., where Mr. DeDee had been the president and chief executive. Ms. Hinchman had traveled from Chicago to see a student perform there and was pleasantly surprised when a friend introduced her to Mr. DeDee.
