Albert Einstein Autographed Signed Letter To His Son.

Autograph letter signed (“Papa”) to his son Hans Albert (“Lieber Adu”). In German. Einstein is writing to his eldest son regarding his planned trip to Switzerland to visit his relatives. Einstein offers him $500 for the trip, under the condition that he returned to the United States. “To lend money is not a good thing. I would be very glad if you could arrange to take Maja (Einstein’s sister) along with you.” The letter concludes: “I felt several times not very well; it is just as with an old Ford (a little tottering). But the work is getting along fine and I am also satisfied as far as my personal life is concerned.” In near fine condition.
