During an appearance at the American Library Association Annual Conference, Sonia Manzano, who has played the character Maria on “Sesame Street” for 44 years, announced she would be retiring from the PBS children’s television series.

Manzano joined the show in 1971 and became a series regular in 1974. As Maria, she ran the Fix-It-Shop with her TV husband Luis (Emilio Delgado). During her time with the show she won 15 Daytime Emmy Awards as a scriptwriter and was nominated twice for “Outstanding Performer in a Children’s Series.”

When the news broke, many fans took to Twitter to let the 65-year-old actress and author know that she’ll be missed. In response to one tweet, Manzano said that she would be open to returning for the show’s 50th anniversary.

Manzano is currently promoting her new memoir, "Becoming Maria: Love and Chaos in the South Bronx," which will be published in August.
