Google's search website was updated Tuesday for the first day of National Hispanic Heritage Month with a new Doodle to honor Puerto Rican civil rights pioneer Felicitas Mendez. Hispanic Heritage Month began as Hispanic Heritage Week. Hispanic Heritage Week was established by legislation sponsored by Rep. Edward R. Roybal of Los Angeles and was signed into law by President Lyndon Johnson in 1968. In 1988, the commemorative week was expanded to a month (September 15 to October 15) by legislation signed into law by President Ronald Reagan.
