Albert Einstein — Biography

The life and legacy of Albert Einstein.

Albert Einstein was born on March 14, 1879, in Ulm, Germany, to Hermann and Pauline Einstein. His family moved to Munich when he was an infant, where his father and uncle operated an electrical equipment manufacturing business. Einstein showed early curiosity about mathematics and science, though his performance in school was uneven. His family moved to Italy in 1894, but Einstein remained in Munich to complete his studies. He eventually enrolled at the Polytechnic in Zurich, Switzerland, where he studied physics and mathematics.

After graduating in 1900, Einstein faced difficulty securing academic positions. He worked as a technical expert at the Swiss Patent Office in Bern beginning in 1902, a position that provided stability while he pursued independent scientific research. During his time at the patent office, Einstein published four groundbreaking papers in 1905, his "miracle year," including work on the photoelectric effect, Brownian motion, special relativity, and the famous equation E=mc². These papers established him as a major scientific figure and led to academic appointments across Europe.

Einstein's most significant achievement was developing the General Theory of Relativity, published in 1916, which revolutionized understanding of gravity, space, and time. His prediction that light bends around massive objects was confirmed during a solar eclipse in 1919, bringing him international fame. In 1921, he received the Nobel Prize in Physics, though the award cited the photoelectric effect rather than relativity.

In his personal life, Einstein was married twice. His first marriage to Mileva Marić, a fellow physicist, ended in divorce in 1919. He married Elsa Löwenthal, his cousin, the same year. Einstein had two sons from his first marriage. He was known for his unconventional personality, distinctive appearance with wild hair, and pacifist views. He spoke out against militarism and later fled Nazi Germany in 1933, eventually settling in Princeton, New Jersey.

During World War II, Einstein signed a letter warning President Roosevelt about the possibility of Nazi Germany developing atomic weapons, contributing to the initiation of the Manhattan Project. He spent his final years at Princeton's Institute for Advanced Study, continuing theoretical research while expressing concerns about nuclear weapons and advocating for peace.

Einstein died on April 18, 1955, in Princeton at age 76. His scientific theories fundamentally transformed modern physics and remain foundational to contemporary science. His name has become synonymous with genius, and his contributions continue to influence physics, cosmology, and technology in the twenty-first century.
