to Einstein, Mar. 17, 1918: “My state of health is now such that I can lie down quite well at home; although I can’t get up, I can very well occupy myself quite a considerable amount with the children, and this makes me very happy and contributes much to my well-being.” Einstein to Heinrich Zangger, May 8, 1918.
