The personal effects of Yakov Bogopolsky and his son, Emil Bolsey, have left us with a considerable amount of archival material concerning their lives and activities. For the most part, this can be attributed to the fact that Yakov was sent to Switzerland to continue his studies shortly before the outbreak of World War I and was never able to return. For the rest of the family, the war and the revolution that followed it, followed in turn by the second World War and the Holocaust, meant decades of deprivation and persecution. To date, we have little documentation about their lives, but, thanks to the contributions of relatives in Russia, we are rapidly expanding our archives.
