Hector Berlioz (1803-69) Composing The Trojans Lionello Balestrieri (1872-1958)

The picture has something of this: people, man, portrait, elderly, scientist, sit, easel, woman, book bindings, Renaissance, furniture.
Perhaps it’s a painting of a man in a suit and tie sitting at a desk with a piano in front of him and a woman standing next to him.
