Without quoting directly from the text give me a summary of Rita Moreno's greatest achievements.

Rita Moreno is an actress, dancer, and singer from Puerto Rico whose career spans several decades. She is one of the few people to have accomplished EGOT status by winning an Emmy, a Grammy, an Oscar, and a Tony. She is most well known for being the first Latin American woman to receive an Oscar for her work in Westside Story in 1961.
