* Einstein’s salary after tax was 13,000 marks. Inflation was beginning to set in, and the value of the German mark had fallen from 24 cents in 1914 to 19 cents in January 1918. One mark at the time would buy two dozen eggs or four loaves of bread. (A year later, the mark would be worth only 12 cents, and when hyperinflation began to rage in January 1920 only 2 cents.) Mari’s stipend of 6,000 marks in January 1918 was thus worth about $1,140, or just under $15,000 in inflation-adjusted 2006 dollars. His proposal was to increase this by 50 percent.
