What's the name of the movie where the doctor discovers penicillin and the towns people at the end all go up to his house and thank him for all he has down to help the town. It's a black and white movie. He helps the town by funding a hosptial on IOU's. He also takes in a girl and his son ends up marrying her in the end! At the end of the movie after the towns people have thanked him, he dies. PLEASE HELP ME!!
