Immigration and Nationality Act of 1965

The Immigration and Nationality Act of 1965, also known as the Hart–Celler Act and more recently as the 1965 Immigration Act, is a landmark federal law passed by the 89th United States Congress and signed into law by President Lyndon B. Johnson. The law abolished the National Origins Formula, which had been the basis of U.S.Wikipedia

9. Congressman Emanuel Celler, the bill’s House sponsor, had dedicated his life to ending immigration quotas. 

Celler served in the House of Representatives as the Congressman from Brooklyn for decades. The Democrat was in the House when the Johnson-Reed Act of 1924 established the country’s strict, racist quota system of immigration. As a representative of a district full of Eastern European immigrants, and as a Jewish representative himself, Celler cared deeply and passionately about justice in immigration. He spoke furiously against the Johnson-Reed Act when it passed, then fought against its principles for the next four decades, until finally, he was able to sponsor the bill that undid it.
