How long was Albert Einstein married for?

Albert Einstein (/ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.

The Swiss (German: die Schweizer, French: les Suisses, Italian: gli Svizzeri, Romansh: ils Svizzers, Russian: Шведы) are citizens or natives of Switzerland. The demonym derives from the toponym of Schwyz and has been in widespread use to refer to the Old Swiss Confederacy since the 16th century.

Although the Swiss Confederation, the modern state of Switzerland, originated in 1848, the period of romantic nationalism, it is not a nation-state, and the Swiss are not usually considered to form a single ethnic group, but a confederacy (Eidgenossenschaft) or Willensnation ("nation of will", "nation by choice", that is, a consociational state), a term coined in conscious contrast to "nation" in the conventionally linguistic or ethnic sense of the term.

The Einstein family is the family of the famous scientist Albert Einstein. Einstein's great-great-great-great-grandfather, Jakob Weil, was his oldest recorded relative, born around the turn of the 18th century, and the family continues to this day. Albert Einstein's great-great-grandfather, Löb Moses Sontheimer (1745–1831), was also the grandfather of the prominent tenor Heinrich Sontheim (1820–1912) of Stuttgart.

Albert's three children were from his relationship with his first wife, Mileva Marić, his daughter Lieserl being born a year before they married.

Hans Albert Einstein (May 14, 1904 – July 26, 1973) was a Swiss-American engineer and educator, and the second child and first son of Albert Einstein and Mileva Marić. He is best known for his research on sediment transport. Hans Albert Einstein's papers are held at the Water Resources Collections and Archives in the University of California, Riverside Libraries.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.

Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.

A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.

Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
