Six Moments From the Archive that Shaped A Family. Albert Einstein lived with the Winteler family for one year, and stayed bound to them for life, through love, marriage, and tragedy.
A 24-year-old Swiss university student named Jost Winteler predicted Hitler. He died four years before he was proven right.
In 1874, a young Swiss graduate studying in Germany named Jost Winteler sat down and wrote a poem. It was not a sentimental poem. It was a warning — about a darkness rising in Germany’s bosom. He wrote it fifty-nine years before Hitler took power.
Forty years later, they were still talking about what they lost.
Her name was Marie Winteler. She was eighteen. Together with Albert, they played Mozart duets in the evening. A romance quickly blossomed into passionate love.
It didn’t last — Albert chose physics over Marie.
Twelve years later, in 1909, he wanted her back.
He called one “Mama.” He called another his “adopted sister.” History called them nothing at all.
He tugged at Pauline’s apron strings just to make her scold him. He called Rosa his adopted sister and meant it. He recoiled when Anna was like the strict aunt, willing to tell him what he didn’t want to hear. Three women who never existed in a century of Einstein biographies.
On a warm November evening, everything changed.
Thousands were still making their way home from the Rosengarten cemetery — two days after All Saints Day, chrysanthemums and wreaths still fresh on the graves — when gravediggers appeared among them and began digging three new holes in the ground.
That afternoon, Winteler and Einstein family members looked down at a double grave.
He redesigned the universe. They redesigned their lives — in the hills near Florence.
Albert’s sister Maja and her husband Paul Winteler arrived in Florence in the spring of 1921 — not as tourists, but as artists. In their late thirties they made a conscious, almost audacious decision: to build their own paradise.
And they did. Their hillside estate above Florence was part working farm, part salon, but a living dream. “It is a bliss to be alive,” Maja wrote one morning with birdsong in the air and Florence spread out below.
What ended it changed humanity itself.
She flew toward him when she saw him.
One morning in March 1939, tugboats pulled a French ocean liner into New York Harbor. Through the darkness, Maja Einstein-Winteler watched the fishing trawlers appear, then Long Island’s lights stretching impossibly wide. Passport control came at 2 a.m.
After 40 years together, she had left her husband Paul on a platform in Florence weeks earlier. She told him she’d be back in six months. Fate had other ideas.
