I have no idea if this is accurate.

Oh wait, its a dumb internet quiz

Richard Wagner was very possibly the single most influential composer of the mid-tolate 19th century. He was primarily a composer of opera, but as he believed in complete and total works of art, he would write the libretto and the music, cast the show, direct the rehearsals, design the staging lighting and costumes, and do everything else to make the things work. Yet for all these creative and management skills, Wagner was in fact an utter sleazebag. He had a regular habit of sleeping with the wives of the conductors with whom he worked, and his anti-Semitic pamphlets were an inspiration to Hitler. It's best to just ignore Wanger the man and pay attention to Wagner the artist. If you can handle four-hour operas.
A few key works: Tristan und Isolde, Der Ring des Nibelungen, Der Fliegende Hollander, Die Meistersinger
