Autographs and comes with their Certificate of Authenticity. Leopold Infeld was born into a family

of Polish Jews in Kraków, then part of the Austro-Hungarian Empire (it

rejoined an independent Poland in 1918). He University and

from 1920 in Berlin, where he had engaged Albert Einstein's help[2] to gain admission to the University of Berlin. He

obtained a doctorate in 1921. In 1933 he left for England, then for the United States and Canada after the death of his second

wife, Halina. Infeld was interested in the theory of relativity. He

was awarded a doctorate at the Jagiellonian University(1921),

worked as an assistant and a docent at the University of Lwów(1930–1933)

and then as a professor at the University of Toronto between

1939 and 1950. He collaborated with Albert Einstein at Princeton University(1936–1938).

The two scientists jointly formulated the equation describing star movements as

well as concurrently writing the book The Evolution of Physics. After

the first use of nuclear

weapons in 1945, Infeld, like Einstein, became a peace activist. Because of his activities, he was unjustly

accused of having communist sympathies. In 1950 he left Canada and returned

to communist Poland. He felt

he had an obligation to help science in Poland recover from the ravages of

the Second World War. He

served as President of the Polish Physical Society between

1955 and 1957. In the staunchly anti-communist climate of the time, many in the

Canadian government and media feared that working in a communist country; he

would betray nuclear weapons secrets.

He was stripped of his Canadian citizenship and

was widely denounced as a traitor. In actuality, Infeld's field was the theory of relativity—not

directly linked to nuclear weapons research.

After Infeld's return to Poland, he requested a leave of absence from the University of Toronto. His

request was denied, and Infeld resigned his post. In 1995 the University of

Toronto made amends and granted Infeld the posthumous title of professor emeritus. Upon

his return to Poland, Infeld became a

professor at the University of Warsaw, a

post he held until his death. The Born–Infeld model was

named after Max Born and Leopold Infeld, who

first proposed it. The Infeld-Hull Factorization Method describing general sets

of solutions to the Schrödinger equation. Infeld

was one of the 11 signatories to the Russell–Einstein Manifestoin

1955 and is the only signatory never to receive a Nobel Prize. In 1964 he was one of the signatories of the

so-called Letter of 34 to Prime

Minister Józef Cyrankiewicz regarding

freedom of culture. Infeld is the author of Quest: "An

Autobiography" and the biography "Whom the Gods Love: The Story

of Évariste Galois." In

1939 he married Helen

Schlauch, an American mathematician.
