112 Mercer Street, commonly known as Einstein’s House, is the former home of physicist Albert Einstein in [[Princeton]], New Jersey. He resided at this address from 1933 until his death in 1955, continuing his work and becoming a fixture in the Princeton community. The house remains a private residence today, though its historical significance draws considerable interest.

== History ==

Albert Einstein emigrated to the United States in 1933, fleeing the political climate in Nazi Germany. He accepted a position at the [[Institute for Advanced Study]] in Princeton, a newly established center for theoretical research. Initially, he rented a house at 87 Mercer Street, but soon sought a more permanent residence. In 1935, he purchased the house at 112 Mercer Street, a relatively modest dwelling for a figure of his stature. <ref>{{cite web |title=NJ.com |url=https://www.nj.com |work=nj.com |access-date=2026-02-25}}</ref>

The house quickly became a hub of intellectual activity. Einstein frequently hosted colleagues, students, and visitors, engaging in discussions on physics, philosophy, and world affairs. He maintained a relatively simple lifestyle, preferring comfortable practicality to ostentatious displays of wealth. Despite his fame, Einstein valued his privacy and sought to maintain a degree of anonymity in Princeton. He became a naturalized citizen of the United States in 1940, though he continued to maintain a strong connection to his European roots. The house served as his base of operations as he continued to refine his theories and advocate for peace and social justice.
