The date of Rubinstein’s death 3
Our member Wilfried Krebbers took another step towards solving the problem of the anniversary of Rubinstein's death. In the Belgian daily newspaper Le Soir of March 17, 1961, he found an obituary notice from Rubinstein on page 7. The date of death is mentioned there as March 14, 1961.
This should be another indication that Rubinstein died on March 14th and not on March 15th.
