Joaquín Monserrat Llarden, known as Pacheco (5 April 1921 - 5 November 1996)[1] was a Spanish comedian and host of children programs.

It was in Cuba that he met and befriended a local actor named Luis Aguad Jorge, who would later join him many times on Puerto Rican television as El enanito Holsum.

In 1960, he moved to Puerto Rico and was hired as a scriptwriter and comedian in the program Pacheco, Detective Privado.

In the program, Monserrat (now known simply as Pacheco) gave the children advice, interviews, and showed cartoons.

For 13 years, he hosted the Jerry Lewis MDA Telethon in the island and occupied the position of Honorary Vice President.
