After her marriage Mileva Mari took the name Mileva Einstein-Mari. Thus, before, during, and after her marriage her last name ended in Mari. Solely for simplicity, we use Mari when referring to her by last name.

We use the following abbreviations throughout:

Who was the real Mileva Einstein-Mari, the wife of the famed physicist Albert Einstein? Trained alongside Einstein in physics and mathematics, what role did she play, if any, in the famous papers of her husband, which transformed contemporary physics? Was she an unsung contributor or even a co-author, a sounding board, the top fiddle, a glorified assistant, an unglorified housewife, the one who made it all possible?

What does it even matter? It matters, of course, because Einstein's work and his theories of relativity, quantum theory, and atomic theory formed the foundations of contemporary physics. Without the true story of what really happenedhow these fundamental theories came aboutwe cannot fully understand their historical significance. Moreover, we cannot bestow credit where credit is due for these achievements, especially when we recognize how often the contributions of women scientists, especially the scientific spouses and partners of celebrated male scientists, are overlooked, forgotten, and even suppressed.

Much has been written over the past decades in support of one or more of the above perspectives on Mileva Einstein-Mari, often with fervent certitude This book is an excursion into these heavy waters, a journey guided by the historical urge to get it rightor at least to get as close as possible to rightfor the sake of Mileva and Albert, and for the sake of the history of contemporary physics. Such a journey becomes all the more important in an era of deliberate falsehoods, fake news, and alternate facts. The ballast of mounting documentary evidence that has become available during the past decades about these two extraordinary people and their work and activities keeps this ship on course.

It is well known that Albert Einstein, the world-famous scientist declared the person of the century by Time magazine, was married. But until the 1990s, few people knew that he had two wives, the first of whom was trained in mathematics and physics. Einstein's nonscientific second wife, Elsa, did become widely known, especially in the United States, when she accompanied her husband on several well-publicized visits during the 1920s, then settled with him in Princeton in 1933 (she died three years later). The two had married in 1919, the same year that the first public confirmation of Einstein's theory of general relativity, one of the greatest achievements of the twentieth century, brought him worldwide fame.

But it was his first wife, Mileva Einstein-Mari (approximately pronounced Mar-itch), who accompanied and supported him intellectually and emotionally throughout the difficult early years of his rise from a beginning physics student in 1896 to the top of his profession by 1914. Little was known about her or his children with herand there was little interest in finding outuntil the discovery in 1986 of her correspondence with Einstein brought Mileva Einstein-Mari to widespread public attention. The letters had been in the possession of the Einsteins first son, Hans Albert Einstein, and his family in Berkeley, California.

The story of Mileva Einstein-Mari encompasses many facets of great human and scientific interest related to the struggle of women in science as revealed by observing one woman's struggle to realize her dreams for a scientific career and examining a married couple's scientific and personal partnership that unfortunately did not succeed.
