Max Delbruck had reached the stage of his career where he should apply for a permanent university post. By then all formal correspondence of that kind should be signed off with 'Heil Hitler'
Delbruck (from an upper class Protestant family) was reluctant to do this. He consulted a friend.
How would you normally expect to sign? asked the friend
Oh um - Yours very respectfully said Delbruck
You wouldnt mean that either said the friend
Delbruck signed the letter
