Robert Lopez is an American songwriter for musicals and playwright, best known for co-creating The Book of Mormon and Avenue Q, and for co-writing the songs featured in the Disney computer-animated films Frozen, its sequel Frozen II, and Coco, with his wife Kristen Anderson-Lopez. He is one of only nineteen people who have won an Emmy, a Grammy, an Oscar and a Tony Award, nicknamed by Philip Michael Thomas in 1984 as the "EGOT". He additionally holds the distinctions of being the youngest person to win an EGOT, and winning the awards across the shortest period of time: he won all four in the span of ten years and completed the set at the age of 39. He is also the only person to have won all four awards more than once, having won two Oscars, three Tonys, three Grammys, and four Emmys. With a second set of competitive wins beginning with his June 27, 2010 Emmy and concluding with his March 4, 2018 Academy Award, he has broken his own 'fastest to complete' record, establishing a new fastest EGOT interval at 7 years and 8 months.

The Book of Mormon is a musical comedy with music, lyrics, and book by Trey Parker, Robert Lopez, and Matt Stone. The story follows two missionaries of the Church of Jesus Christ of Latter-day Saints as they attempt to preach the faith to the inhabitants of a remote Ugandan village. The earnest young men are challenged by the lack of interest from the locals, who are distracted by more pressing issues such as HIV/AIDS, famine, female genital mutilation, child molestation, and oppression by the local warlord.
