I recently watched a documentary about the stripping of Jewish wealth by the Nazis running up to and early in the second world war. One of the companies it looked at is Fromms, currently the second largest condom manufacturer in Germany* and at one time the largest. In 1916 Julius Fromm invented a way to make seamless condoms. Until that time condoms were moulded, which made them both thick and seamed (ribbed, but not for your pleasure). In fact, and brace yourself for this, they were sufficiently resilient that they were reusable.
By 1938 it was obvious to Fromm that it was time to leave, so he put his business up for sale for a million Reichsmarks – somewhat less than the business was worth, but not a terrible deal. Perhaps because all the potential purchasers also knew that change was coming he was unable to sell ‘legitimately’, and in the end was forced to sell to Hermann Göring’s godmother, Baroness Elisabeth von Epenstein. Let me repeat that; Hermann Göring’s godmother used to be Germany’s biggest condom manufacturer.
(*i.e. they are the second biggest company. I have no information about the size range that they offer.)
