Who is known as "the father of film music"?

What musicals or film scores did Max Steiner compose? I am disappointed that it didn't name any in the explanation.

Until sound film, the sound track was provided live by theatre musicians. Steiner arrived in Hollywood just as movies included their own music.

Deborah, Gone With The Wind, for one. The explanation is sadly lacking pertinent information.

Everyone must father something in life.

interesting clue considering that all the cameras shown in silhouette are ALL still cameras

Max was dope.

only name I recognised!
