In 1897, Mileva Marik (pictured below), a talented girl from Titel, Austria-Hungary, entered Swiss Federal Institute of Technology in Zurich to study mathematics and physics. In 1897, five female students were studying theoretical physics at Swiss Federal Institute of Technology, and Mileva was only female among them. Mileva's unique temperament and professional knowledge deeply attracted Einstein.
When subsequent generations parsed Einstein's love letters to Mileva, young Einstein's fiery passion was still felt through slightly yellowed paper.
"How lucky I am to have found you, a being equal to me, as strong and independent as I am! I would be lonely with anyone but you... makes me think that life - this is a really meaningful thing, if there was a little life in mind too, made of flesh and blood, that would be great!"
After six years of romance, Einstein and Mileva officially married in 1903. They had a daughter and two sons. Einstein had no children after his second marriage. So, how did Einstein feel about his children and what were their life experiences?daughter: Liesel Einstein
After Einstein and Mileva fell in love, they became inseparable and were blinded by love, so that their studies fell sharply.
In 1900, Einstein passed mediocre and Mileva failed. What's even more serious is that Mileva is pregnant. At time, out-of-wedlock pregnancy was a scandal that meant young scientist's future was in jeopardy.
For sake of future of Einstein, Mileva resolutely returned to her parents, where she gave birth to a child named Liesel. Neither Einstein nor Mileva said anything about Liesel situation. It is assumed that Liesel died or was given up for adoption. But what is certain is that Einstein never met his daughter.Eldest son: Hans Einstein
In second year of marriage between Einstein and Mileva, eldest son Hans Einstein was born. As a child, Hans had a good relationship with his father, but after Einstein and Mileva separated, relationship between father and son was once bad.
In terms of scientific achievements, Einstein is a giant, but in terms of private life, Einstein is really a "thug". A few years after his marriage to Mileva, Einstein made a lot of scandalous news, and later fell in love with his cousin, cousin Elsa (their mothers were sisters). In 1914, Einstein and Mileva officially separated: Mileva lived in Switzerland with her two sons, while Einstein lived in Berlin with his cousin Elsa.
Einstein once planned to go on a trip, but did not discuss it with Mileva, Hans wrote, blaming his father:
"You should tell your mom about trip because I can't make up my mind. If you don't respect your mom, I won't go with you."
After receiving letter, Einstein became very angry and immediately canceled plan to see his son, writing back:
"Your letter is too unreasonable, I will not go to you so as not to part."
Of course, later Einstein quickly regretted that he should not be angry with his son. In a letter to a friend, he said: "I made a big mistake. A reasonable person would not do this."
In 1919, Einstein and Mileva officially divorced, and their two sons lived with their mother. Due to divorce of his parents and fact that his father lived in Berlin, Hans Einstein was educated by his mother. Of course, Mileva herself is also a genius, and later physicists suspect that some of work on special relativity was done by Mileva.
By inheriting his parents' genes, coupled with his mother's proper education, Hans Einstein (pictured above right) graduated summa cum laude from Swiss Technical School of Zurich with a degree in civil engineering. However, Einstein was very unhappy with Hans' career choice, calling it a "disgusting idea". From Einstein's point of view, engineering is a purely practical discipline, a low-level discipline, while theoretical physics is a high-level discipline.
After leaving school, Hans continued to study while working, and in 1936 received a doctorate in engineering.
The reason Hans chose civil engineering was due to his mother or his own preferences, but one thing is certain: Einstein was away from him for a long time, and abusive relationship between his parents was reason Hans did This. don't choose Einstein. An important reason for Stan's Way.
In 1927, Hans met Frieda Knecht and married her, but Einstein hated his daughter-in-law Frida utterly, claiming that Hans had married a woman who was "too mediocre" with whom I don't even want to have any conversations. Frida wrote to Hans in a letter:
"You have such a bright personality, but it's a pity that you marry such a wife, but if it makes you happy, what should I do?"
For this reason, Einstein urged Hans not to have children for simple reason that he believed that Hans and Frieda would definitely divorce, "that day will surely come." Einstein judged others by himself, thinking that as soon as Hans and Frida had children and divorced, this would inevitably bring a lot of trouble.
In fact, Hans and Frieda had a happy marriage. Frida died in 1958. They had three children and adopted a daughter, Evelyn Einstein. Two sons died young. Only Bernhard Einstein grew up and later received a doctorate in engineering, and his adopted daughter Evelyn Einstein had a master of arts and spoke four or five languages. Hans married a second time only a few years after Frida's death.
When anti-Semitism intensified in Germany, Hans left Germany in 1938 and emigrated to United States at Einstein's urging.
In United States, Hans achieved many amazing achievements, including theory of sediment mechanics, concept of formation sand and wash quality, and a calculation method for determining sand wave resistance from measured river data, which made him an authority on field of hydraulic engineering, and his main works include "Sediment bearing capacity of flow in an open channel", "Hydrodynamic forces on rough sidewalls", "Complex resistance to water flow", "River bed resistance", etc.
Hans has received many awards for this: a Guggenheim Fellowship, a research award from American Society of Civil Engineers, a hydraulics research award from USDA, and a Stevens Award... as important as Nobel Prize.
Hans later became a professor of hydraulic engineering at University of California at Berkeley. Qian Ning (pictured above), M.Sc. in Water Management and Sedimentation in China, studied under Hans. Together they developed dynamic sediment modeling. test method, it was called "Einstein-Channing method".
In 1973, Hans died of a heart attack in Massachusetts, USA, at age of 69.Youngest son: Edward Einstein
In 1910, Einstein's second son, Edward, was born. Unlike Hans, Hans still lived with Einstein as a child, while Edward stayed away from Einstein almost all time, which set stage for a bad relationship between two.
Edward was only 4 years old when his parents divorced and 9 years old when his parents divorced. Because he lives in Switzerland, Edward rarely sees his father. As a teenager, Edward wrote letters to his father with great interest, but he did not know if Einstein ignored them or ignored them, so he did not answer letter. Later, there was no connection between Einstein and Edward.
Edward grew up to be an excellent pianist and diligently studied medicine and psychiatry. But, unfortunately, this happened: in 1929, Edward suffered from a very severe form of schizophrenia (Edward's mental illness must have been inherited from his mother's family, and he had it since childhood, but it was not serious before), and he was cruelly tortured by disease . This year, Einstein specifically went to visit after learning about this, and later his second wife Elsa recalled:
"After Einstein visited his son, he was very saddened. He could not accept this fact more than anyone else. Although he pretended to be very strong on surface and did not care, there was a lot of pain in him in his heart. The blow is too strong."
After Einstein left Europe in 1933, father and son never met again. So far, there is no chance to improve relations between father and son.
Edward (pictured above) resented his father for another important reason. Einstein asked for a divorce from Mileva, which came as a bolt from blue for Mileva. share Nobel Prize. In 1921, after Einstein received prize, he gave part of it to Mileva, but exact amount is still a mystery. But in order to take care of two children, be responsible for their education and treat Eduard, Mileva spent almost all her savings, and later she had to earn a living by teaching piano. Taking care of her seriously ill younger son, earning a living and earning money, Mileva was very unhappy in last years of her life.
Up to about 1948, Mileva was half paralyzed and in despair. Finally, in 1948, she died of a stroke and was buried in an unmarked grave in Zurich. After Mileva's death, Edward was sent to a psychiatric hospital in Zurich for treatment, he died in 1965 and never married.

After Einstein passed away, he donated all copyrights to related papers and other property to Hebrew University of Israel, earning approximately US$10 million in copyright revenue each year. Evelyn is Einstein's adopted granddaughter. After divorce, she fell into poverty. She claimed to have collected things in a trash can. She publicly complained that Einstein did not leave a penny to her family, including Einstein's grandson, physicist Bo Earnhard, who also did not receive an inheritance.
Looking back at Einstein's life, he is admirable academically, socially opposed to war, and nationally concerned about future of Jewish people. However, in his personal life, Einstein really was not a worthy husband and father. Perhaps this "gold has no legs and no perfect people", and saints are also insignificant.
