Albert Einstein was born in 1879 in Germany and died in 1955 in USA.

Albert Einstein won the 1921 Nobel Prize for physics "for his services to theoretical Physics, and especially for his discovery of the law of photoelectric effect."

The most important year of his life was 1905, when he published four revolutionary articles in 'Annalen der Physik,' the leading physics journal in Europe at that time. Within seven months he published papers in three different fields in physics:
"Quantum of light and photoelectric effect" in March,
"Brownian motion and atomic theory" in May,
"The special theory of relativity" in June, and
"Equivalence of mass and energy" in September

In the same time Albert was working 6 days a week at the Patent office in Bern, and preparing his dissertation on determining the number and size of ions.

Was it possible for one man to have the entire job done, or he had a helper besides him?

The New Science article from March 1990 "Was the first Mrs. Einstein a genius too?" shows that more and more evidence is discovered to sustain the idea that Mileva Maric was a major contributor to Einstein's work from the crucial period in his career.

Mileva and Albert met in 1896 as students at the Swiss Federal Institute of Technology in Zurich, Switzerland. She was the only woman in the entire Mathematics and Sciences Department. Mileva and Albert got married in 1903 and divorced in 1919.

There is evidence supporting the idea that Mileva worked with Albert on his famous papers published in 1905. For example, in "In remembrance of Albert Einstein" the author, soviet physicist Abraham Joffe, claims that he has seen the original submitted papers being signed by Einstein-Marity. Another source of evidence is the correspondence between Albert and Mileva from 1897 to 1903, published in "Albert Einstein-Mileva Maric The Love Letters". The letters show that Albert have discussed his scientific ideas with Mileva, whom he considered intellectually equal. One of the big Mileva Maric supporters is Senta Troemel-Ploetz, a research linguist with the German Research Society in Bonn, who wrote the article "Mileva Einstein Maric, the women who did Einstein's mathematics."

The main opposer to the idea of Mileva's contribution to Albert's work is John Stachel, professor of physics at Boston University, and editor of Einstein's collected papers.

Missing of the original Special Relativity manuscript and the unproportionally small number of Mileva's letters to Albert, make the idea of deliberately keeping Mileva's work out of sight more possible.
