Louie first appeared on-screen in the Sesame Beginnings direct-to-video series, as a stay-at-home dad and the primary caregiver to his infant son. (Sesame Beginnings takes place in a fictional "past" when the characters were babies, which we can assume in Elmo's case is about three years earlier than the Sesame Street "present".) Louie plays the saxophone, and fills Baby Elmo's daily routine with rhythm. He organizes a baby band with Elmo's play group.
Flash-forward to the present for Sesame Workshop's direct-to-video special for military families, Talk, Listen, Connect. In this 2006 special, Louie has joined the military, and is deployed far away. The special doesn't explicitly state that Louie is in the military; instead, it's explained that Louie is away "working" and "helping people". Elmo's mom Mae helps Elmo to understand why his father is away, and uses a daily routine to help Elmo cope with the separation.
Louie's appearance was changed after the initial Sesame Beginnings releases, starting with Talk, Listen, Connect and continuing in the later Beginnings DVDs (such as Exploring Together). Louie's new look included a different hair style, different facial hair (a goatee rather than a mustache), and a new wardrobe. However the older, mustached, Louie design was seen in Elmo's Potty Time.
Louie initially appeared solely in direct-to-video and outreach productions, but began making recurring appearances on the show itself starting in season 47.

Elmo's dad had been seen in a number of books, and like Grover's Mommy, his appearance varied widely according to the artist. In such titles as Elmo Gets Homesick and When Is My Birthday?, Elmo's dad resembles an adult version of Elmo. However, in the more recent illustrations and books, the character holds true to the current Louie, as seen in Sesame Beginnings.
The first incarnation of Elmo's dad to be seen on television was in the "Birthdays" episode of "Elmo's World," in which Dorothy imagines Elmo on the day of his birth in a dream sequence. As with all such "Elmo's World" sequences, all of the characters are seen from Dorothy's point of view -- that is, as an altered version of Elmo. In this incarnation, Elmo's parents look just like Elmo and are referred to as George and Gladys (named after the parents of Elmo's puppeteer Kevin Clash).
- Louie Monster is the first, and only, major character in the Sesame Street universe performed by Muppeteer Bill Barretta.
- Louie was performed by Tyler Bunch in Learning is Everywhere and Bedtime with Elmo before he became Louie's permanent performer starting with Elmo's Travel Songs and Games. Barretta's last performance as Louie was in When Families Grieve.
