There's been a bit of a conspiracy surrounding Einstein's first paper on relativity, "On the Electrodynamics of Moving Bodies" from 1905 that suggests that the physicist's wife at the time, Mileva Marić, co-authored the paper but did not receive any credit. New analysis from Galina Weinstein at The Centre for Einstein Studies at Boston University suggests that the story is not corroborated by historical or primary source documents. It turns out the that controversy was primarily fueled by two pieces of evidence: a 1901 letter from Einstein to his wife saying that he was "bringing our work on relative motion to a successful conclusion!" and a misunderstanding about a Swiss custom that led to the idea that the scientist signed his papers as "Einstein-Marity" (Marity being the Hungarian maiden name of his wife, Mileva). The new analysis says that Mileva never spoke of anything substantial in physics to Einstein in multiple letters to him, and that she indeed wasn't a talented physicist or mathematician herself. It's a good story, but, for now, it seems that Mileva was merely a "sounding board" for Einstein during his work on the famous paper.
