Ancestry.com has posted copies of German telephone books from 1915 to 1981
- including Albert Einstein's phone number while he was a university professor in Berlin.
Back then, just asking for 2807 got you a direct line to the physics genius.
The genealogy Web site got Einstein's number when it scanned dusty phone books kept at the German National Library.
Adolf Hitler's longtime companion, Eva Braun, also shows up in the 1937 Munich directory.
The Web site says the records will come in handy for the nearly 50 million Americans of German heritage hoping to trace their ancestors.
