Wissenschaft am Abgrund: AE als oeffentliche Person ab 1919
Friends give Einstein the dinghy as a fiftieth birthday present in 1929.
It was built by the Berkholz + Gärsch shipyard, has a small auxiliary motor, and is easy to sail.
The boat is docked at his summer cottage in Caputh. Einstein takes extended trips with the boat on the Havel lakes.
