Does "Albert Einstein never did" mean "Albert Einstein never named himself as Einstein-Marity"?
Context:
Ioffe's statements appeared fifty years after he had read the 1905 papers. It stuck with him all those many years that the papers were indelibly signed "Einstein-Marity". How could Ioffe have known that Mileva Maric went by the name of Einstein-Marity, if the name had not appeared on the 1905 papers? Joffe could not have known that Albert went by the name of "Einstein-Marity", because Albert Einstein never did.[34]
