THE EINSTEIN-GROSSMANN COLLABORATION 225

I have a sense of regret that Einstein did not do something for which he had
often demonstrated a talent and sensitivity: to write an obituary shortly after
Grossmann's death. He did so later. In 1955 he wrote of Grossmann, of their
collaboration, and of how the latter had 'checked through the literature and soon
discovered that the mathematical problem had already been solved by Riemann,
Ricci, and Levi-Civita.... Riemann's achievement was the greatest one.' In this
article, Einstein wrote, 'The need to express at least once in my life my gratitude
to Marcel Grossmann gave me the courage to write this ... autobiographical
sketch' [E32].
