'Sesame Street' Actor Emilio Delgado Dead at 81, Played Luis for 40 Years

Emilio Delgado -- the actor best known, and beloved, for his role as Luis on "Sesame Street" -- has died ... TMZ has learned.

Delgado's wife, Carol, tells TMZ he passed away Thursday surrounded by family at his home in NYC. We're told Emilio had recently been in hospice care ... he was diagnosed with the blood cancer Multiple myeloma in December 2020.

Carol says Emilio was still a working actor right up until the pandemic -- playing the lead in "Quixote Nuevo" -- a theater production that had a 3-city run before things were shut down. He also recently did some voiceover work in January 2022.

The beloved Mexican-American actor was a pioneer in children's television, playing Luis, the 'Fix-It Shop' owner for a total of 40 years on the 'Street.' He took a brief hiatus from the show in the late 80s, but returned within a year.

He also performed in live theater throughout his career -- including some "Sesame Street" stage productions -- and has appeared at various conventions over the years.

Emilio was 81.
