Albert Einstein awarded Nobel Prize in Physics

In 1922, Einstein was awarded the 1921 Nobel Prize in Physics,[97] "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect". This refers to his 1905 paper on the photoelectric effect, "On a Heuristic Viewpoint Concerning the Production and Transformation of Light", which was well supported by the experimental evidence by that time. The presentation speech began by mentioning "his theory of relativity [which had] been the subject of lively debate in philosophical circles [and] also has astrophysical implications which are being rigorously examined at the present time." (Einstein 1923)
It was long reported that Einstein gave the Nobel prize money directly to his first wife, Mileva Marić, in compliance with their 1919 divorce settlement. However, personal correspondence made public in 2006[98] shows that he invested much of it in the United States, and saw much of it wiped out in the Great Depression.

In the case of Albert Einstein, his 1921 Nobel Prize was awarded principally for his explanation of the photoelectric effect and not for his work on relativity.

he Nobel Prize in Physics (Swedish: Nobelpriset i fysik) is awarded once a year by the Royal Swedish Academy of Sciences. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others are the Nobel Prize in chemistry, Nobel Prize in literature, Nobel Peace Prize, and Nobel Prize in physiology or medicine. The first Nobel Prize in Physics was awarded to Wilhelm Conrad Röntgen, a German, "in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays (or x-rays)." This award is administered by the Nobel Foundation and widely regarded as the most prestigious award that a scientist can receive in physics. It is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death.
