Albert Einstein wasn't just a floating head with crazy hair thinking about gravity. He was a man. A complicated, often difficult, and deeply romantic man who struggled to balance the demands of the universe with the demands of a dinner table. So, did Albert Einstein have a wife? He actually had two. But saying "he had a wife" is like saying the sun is "kinda hot." It doesn't really cover the gravity of the situation.
His relationships weren't just footnotes in a biography. They were central to his work, especially in the early days when he was just a patent clerk in Bern trying to figure out why time slows down when you move fast.
Mileva Marić: The First Wife and the Forgotten Scientist
Einstein met Mileva Marić at the Zurich Polytechnic in 1896. She was the only woman in his physics and mathematics section. Think about that for a second. In an era where women were barely allowed in higher education, Mileva was holding her own in the most rigorous scientific environment in Europe. She was brilliant. She was also Serbian, slightly older than Albert, and had a limp from a childhood bout of displacement of the hip.
They fell in love over physics. Their letters are a wild mix of "I miss your kisses" and "did you see that paper on electrodynamics?" It was a meeting of minds.
They married in 1903, but the lead-up was messy. Albert’s mother, Pauline, absolutely hated Mileva. She thought Mileva was too intellectual, too "old," and not Jewish enough. Despite the family drama, they pushed forward. But before the wedding, something happened that historians are still trying to piece together. In 1902, Mileva gave birth to a daughter named Lieserl. Albert wasn't there. We only know about her because of letters discovered in the 1980s. What happened to her? Scarlet fever? Adoption? She vanished from the historical record.
By 1905, Einstein’s "Annus Mirabilis" (Miracle Year), he was churning out papers that would change the world. There’s a massive debate among historians like Peter Galison and John Stachel about how much Mileva contributed to his work. While she probably wasn't the "co-author" of relativity in a formal sense, she was his sounding board. She checked his math. She lived the physics with him.

But as Albert’s fame grew, the marriage crumbled. He was traveling, lecturing, and—honestly—flirting. He was a rockstar in a lab coat. By 1914, they moved to Berlin, but Mileva hated it. The atmosphere was cold, and Albert was already seeing someone else.
Then came the "List of Conditions."
If you want to know how bad things got, Albert actually wrote a list of rules for Mileva if they were to stay together for the sake of their sons, Hans Albert and Eduard. It’s brutal. He demanded she keep his clothes in good order, serve him three meals a day in his room, and stop talking to him if he requested it. He essentially treated his wife like an unpaid servant. Not exactly the "sweet old genius" image we see on coffee mugs. They divorced in 1919. As part of the settlement, Albert promised her the money from his future Nobel Prize. He was so confident he’d win it that he literally bet his divorce on it. He won it in 1921 and kept his word, buying Mileva apartment buildings in Zurich so she could support herself and their son Eduard, who struggled with schizophrenia.
Elsa Einstein: The Second Wife and the Gatekeeper
So, did Albert Einstein have a wife after Mileva? Yes, and he didn't look very far. He married his first cousin, Elsa Löwenthal.
They started their affair while Albert was still married to Mileva. Elsa was the polar opposite of Mileva. She wasn't a scientist. She didn't want to talk about the curvature of spacetime. She wanted to take care of Albert. She liked the fame. She liked being the wife of the world's most famous man.

They married in 1919, just months after his divorce was finalized.
Elsa was his protector. She managed his schedule, shooed away unwanted visitors, and dealt with the press. She provided the domestic stability he needed to finish the General Theory of Relativity. But it wasn't a fairy tale. Albert was notoriously unfaithful. He had several well-documented affairs during his marriage to Elsa, including one with his secretary, Betty Neumann.
Elsa knew. She stayed anyway.
There’s a certain sadness to Elsa’s role. She was the one who emigrated with him to the United States in 1933 to escape the Nazis. She was the one who stood by him as he became a symbol of global peace. When she died in 1936 at their home in Princeton, Albert was genuinely distraught. He wasn't great at being a husband, but he relied on her more than he ever wanted to admit. He wrote that he missed her "attachment to him," which is a very Einstein way of saying he felt lost without her.
The Women in the Shadows
To really answer the question of Einstein’s domestic life, you have to look past the two legal wives. After Elsa died, Albert never remarried. He lived out his days in Princeton with his sister Maja and his stepdaughter Margot.

But there was also Margarita Konenkova.
In the 1990s, a cache of letters revealed that Einstein had a serious relationship with Konenkova, who turned out to be a Soviet spy. Whether she was actually "spying" on him or just genuinely in love with him is still a topic for late-night history documentaries. But it proves that even in his twilight years, Albert was looking for connection. He was a man who loved women, loved the company of intellectuals, and seemingly couldn't handle being alone.
Why It Matters Today
Why do we care if Einstein had a wife? It’s not just gossip. Understanding his personal life humanizes the science. It reminds us that genius doesn't exist in a vacuum. It requires support systems, sacrifices (often made by others), and a lot of messy human emotion.
Mileva Marić represents the lost potential of women in science during the early 20th century. Elsa represents the labor required to maintain a public figure’s life. Einstein himself represents the classic struggle between a singular, world-changing obsession and the responsibilities we owe to the people who love us.
He was brilliant at understanding the universe but kinda terrible at understanding the people in his own house.
How to Explore This History Further
- Read the letters. If you really want to get into the weeds, look for The Collected Papers of Albert Einstein. The correspondence between Albert and Mileva is raw, intellectual, and incredibly revealing.
- Visit the Einstein House. If you’re ever in Bern, Switzerland, go to Kramgasse 49. It’s the apartment where he lived with Mileva and their first son. You can see the tiny kitchen and the desk where he revolutionized physics. It makes the "legend" feel very real.
- Look into the "Mileva Debate." Check out the work of Dr. Ruth Lewin Sime or the proceedings from the AAAS (American Association for the Advancement of Science) meetings that discuss Mileva’s role. It’s a great exercise in how history is written—and who gets left out of the footnotes.
- Watch the "Genius" series. While it’s a dramatization, the National Geographic series based on Walter Isaacson’s biography does a solid job of portraying the tension in his marriages without making him a cartoon character.
Einstein’s life was a series of equations, most of which he solved. But the equation of marriage? That’s one he never quite figured out.
