Albert Einstein has Jewish Roots.

Albert Einstein was a theoretical physicist best known for developing the Theory of Relativity, the Philosophy of Science, and his famous Mass–Energy Equivalence formula: E = mc2. He received the Nobel Prize in Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the Law of the Photoelectric Effect."[1]

Birth and Education

Albert Einstein was born in the city of Ulm in Württemberg, Germany, on 14 March 1879.[2][3] He was the son of Hermann Einstein and Pauline Einstein, née Koch.[4][5] Six weeks after his birth, his parents moved the family to Munich, where Albert spent most of his early years and began his education at the Luitpold Gymnasium.[6] Albert's family moved later to Italy, and Albert continued his education at Aarau, Switzerland. In 1896 he entered the Swiss Federal Polytechnic Institute in Zurich and trained to be a teacher in math and physics.[6]
In 1901, Albert graduated from the Polytechnic School and gained Swiss citizenship, but wasn't immediately able to find a teaching position. He took employment as a Swiss patent examiner/technical assistant[6] in Bern.[7] In 1905, he received his PhD[6] from the University of Zurich.[8]


In Zurich, he received his first academic appointment in 1909, as Professor extraordinarius, in 1911 he was a Professor of Theoretical Physics at Prague and returned to Zurich in 1912 to fill a similar position. About 1914, he moved to Berlin and became a German citizen.[6] He held a research professorship there without teaching obligations at the Prussian Academy of Sciences,[7] at the Kaiser Wilhelm Institut für Physik, a position he held until 1933.[9]
His 1919 confirmation of the Theory of General Relativity brought Albert fame and international recognition, which he used as a platform for social concerns.[7] In 1921 he made his first trip to the United States along with Chaim Weizmann to raise funds for the creation of the Hebrew University in Palatine.[7] He and his wife, Elsa, traveled aboard the Rotterdam, naming his "brother" "R. Einstein" as a contact in New York[10] (Albert didn't have a brother, so "R." was probably a cousin).
In 1922, he was awarded the Nobel Prize in Physics for 1921. The delay was due to a conclusion made by the Nobel Committee for Physics that the 1921 candidates had not "met the criteria outlined in the will of Alfred Nobel".[9] The committee argued over the merits of awarding the prize for the very complex and misunderstood Theory of Relativity, which they had trouble proving. They reached a compromise and awarded the prize for Albert's explanation of the photoelectric effect (a phenomenon in which electrons are emitted from a metal sheet only under certain illuminations), which he had published in 1905. The committee wrote to Einstein on 10 November 1922: "...the Royal Academy of Sciences has decided to award you last year's Nobel Prize for physics, in consideration of your work in theoretical physics and in particular your discovery of the law of the photoelectric effect, but without taking into account the value which will be accorded your relativity and gravitation theories after these are confirmed in the future".[11]

Life in America

In 1933, when Hitler gained power, Einstein renounced his German citizenship for political reasons and took a position of Professor of Theoretical Physics at Princeton,[6] at the Institute for Advanced Study.[7] At some point between 1935-1944, Albert's German nationality was annulled by the Nazi regime.[12] Albert and his second wife, Elsa, immigrated to the United States, sailing from Hamilton, Bermuda to New York, New York, on 3 June 1935 aboard the Queen of Bermuda.[3][13] They resided in Princeton, Mercer County, New Jersey, when Albert made his declaration to become a US Citizen in 1936.[14]
In August 1939, Albert wrote a letter to US President Franklin Roosevelt, which "eventually led to the establishment of the Manhattan Project and the US development of the atomic bomb".[7]
On 1 October 1940, Einstein took the Oath of Allegiance, becoming a naturalized United States citizen,[3] while retaining his Swiss citizenship.[7] He was widower and resided in Princeton that year with his (step-)daughter Margot, age 40, his sister Maja Winteler, age 58, and Helen Dukas,[15] (Albert's secretary).[16] In America, he was committed to the process of establishing and maintaining a homeland for Jews, emphasizing the need for equality of rights between Jews and Arabs. He also advocated for nuclear disarmament, world peace, and civil rights for all.[7]
After World War II, Albert was offered the Presidency of the State of Israel, which he declined, although he continued his collaboration with Dr. Chaim Weizmann in establishing the Hebrew University of Jerusalem.[6]

Marriages and Children

Albert married first to Mileva Marić[6] on 6 January 1903.[17][18] She was the daughter of Marija Ruzić and Miloš Marić of Titel in Serbia.[19] Albert and Mileva had a daughter and two sons together:
Albert had started an affair with his cousin Elsa (Einstein) Löwenthal in 1912.[19] As a result, Albert and Mileva divorced in 1919,[6][22] and he married Elsa on 2 June 1919 in Berlin.[5][23][24] Elsa was the daughter of Rudolf Einstein and Fanny Koch, born in Hechingen, Prussia, in January 1876. She was Albert's first cousin through their mothers and second cousin through their fathers.[25] They emigrated to the United States together in 1935 and she died in 1936.[26]

Death and Legacy

Albert Einstein died 18 April 1955 at Princeton, New Jersey.[6] "He had left behind specific instructions regarding his remains: cremate them, and scatter the ashes secretly in order to discourage idolaters." Against his and his family's wishes, the pathologist on call at Princeton Hospital removed Einstein's brain, later receiving his son's approval for the brain to be studied for scientific purposes only.[27]
Albert left a will dated 18 March 1950 leaving his written heritage to the Hebrew University of Jerusalem, which is now showcased in the Albert Einstein Archives there.[28]

In the United States, Einstein was investigated for possible connections to Bolshevik radicals. This is verified by one of the attached images.

Hi there profile managers!

We plan on featuring Albert alongside AJ Jacobs, the Example Profile of the Week, in the Connection Finder on January 6th. Between now and then is a good time to take a look at the sources and biography to see if there are updates and improvements that need made, especially those that will bring it up to WikiTree Style Guide standards. We know it's short notice, so don't fret too much. Just do what you can. A Team member will check on the profile Tuesday and make changes as necessary.

Thanks! Abby

The inline sources on this profile are far from ideal: Wikipedia and Find a Grave. I'll try and add some better sources today and fix it up a bit, but can't promise a great result in one day. If anyone finds sources we can add, please add them in the profile comments as I will be editing until further notice.

Done (for now)! Albert's profile is in much better shape, as are many of his family members. Thanks to everyone who helped!

He spent some time working in the pattent office in Bern, Switzerland. During that time he spent a lot of time working on his own theories and would quickly hide his work whenever his boss came near his desk. He was sitting there at 28 when he had the thought of gravity. He then spent the next 8 years working it all out.

Many teachers, thought he was a daydreamer and one told him he would never amount to anything. Others, especially now, know he was a genius.

When he was in 6th grade they would have a medical student come for dinner on Thursdays. Max Talmud would come and visit and bring books to Albert to read. One of the best ones was a geometry book. It had about as much impact on Albert as the compass his dad had given him.

At 12 he was doing all different kinds of math, not only geometry but also algebra and others. He found it had the structure that made it logical, just like the music he loved.

In college he failed a physics class. This is ironic as he did so much in the field.

He continued his love for sailing and would sail a real boat, sailing when there was wind and writing notes when not.

I came close to failing a physics class in college. Unfortunately, it did not lead to a Nobel Prize.

He was born with a really big head and it scared his mom. She thought it was something wrong with him.

He grew up and everything had to be in his own time. He did not even speak until he was 3 years old, because he always thought in pictures instead of words. He also spoke differently so the maid called him "the dopey one".

He liked to play alone with puzzles, sailing his toy boat or feeding the pigeons. Just thinking was one of his favorite things to do.

At about 4 or 5 he got very sick and was in bed, when his father brought him a compass. It made a big impact on him and his life. He learned from it that everything had order and mystery.

Cards and blocks were turned into structures and tall buildings as he grew. He loved the violin and he saw the structure of the music.

Thank you, Lisa, for your added personal comments here about Albert's early childhood and unique personal characteristics. It is thought by many researchers that Einstein was on the Autistic spectrum, in particular having Asperger syndrome due to his childhood developmental delayed progress. (Autism Wiki, Many high-functioning Aspies are in the math/science/tech field, also musical prodigies such as Australian pianist David Helfgott. ( They contributed much to world human progress. Thanks again!

Hi hun, Yes I have heard that too. I can see where he probably did have it. I have an adult aspie daughter. While reading the information, I kept thinking how much it sounded like her.

HE did not even speak until he was 3 and was the worst behaved student in school. He was fascinated by a simple compass that his father showed him when he was very sick while in grade school. He knew there was something invisible/hidden in how it worked. Everyone disagreed. He as called a foolish dreamer and they requested for him to drop out. He would hide pages with his thoughts on them when his bosses would go by him. he disagreed with the status quo and conventional wisdom. He knew everything was full of energy. His theory showed us the universe. He is quoted "The important thing is not to stop questioning. Curiosity has its own reason for existing.

1. I would question the marriage date for Albert and Elsa. He would not have been able to marry without a divorce degree, and he only got divorced in 1919. The generally accepted date in June 2, 1919.

2. Baden-Württemberg came into being only on March 9, 1952. Hard to have been born there in 1879. Ulm at that time was in the Königreich Württemberg, and that was part of Deutsches Reich.
