Prompt
Generate an image of a senior Danish computer scientist and astronomer, sitting in a library or office surrounded by books and papers, with a thoughtful expression. He is wearing glasses and has a distinguished look, with a hint of a smile. In the background, there are notes or diagrams related to computer science and astronomy, such as flowcharts or equations. The style should be realistic and reminiscent of a 20th-century academic. The man is in his 50s or 60s, reflecting his age during the peak of his career. Include some subtle references to his notable contributions, such as a book on ALGOL 60 or a diagram in the Backus-Naur Form notation.
