Alex[1][2][3] Davidson[4] is a student in Mr. Ratburn's third grade class at Lakewood Elementary School. He is in Mr. Ratburn's class again for fourth grade.[5]


Alex displays a generally quiet and reserved personality. Despite being in Arthur's class since kindergarten, he has never talked with him much at all until fourth grade. This suggests Alex might be shy and tends to prefer to keep to himself. He is a "big reader" and is a fan of the Multiverse book series.

Physical appearance

Alex normally wears a tan collared sweater, long brown jeans, and blue and white sneakers. In "Buster's Dino Dilemma," Alex wears a white shirt that has purple on it, purple shorts with green on it, long green socks, and red and white sneakers.

In the summer, Alex wears a light tanned shirt with a white collar, brown shorts, white socks, and blue and white shoes. He wears green pajamas as seen in "The World of Tomorrow." He also wears blue swim trunks as seen in "Desk Wars."

In the winter, Alex wears long brown pants, a green sweater, a cream colored scarf, cream colored mittens, and dark brown shoes. In the fall, he wears a blue collared jacket with a yellow circle on it.

For formal occasions, he wears a white shirt with a brown tie, a tan shirt over his white shirt, long brown dress pants, and black dress shoes. Another type of formal clothes he wears is a green collared shirt, a red and black striped tie, a vest over his green shirt, dark green dress pants, and brown dress shoes.


Being in Mr. Ratburn's class, it is likely that he has some sort of relationship with the main characters. He is often seen with George and Jenna. He is mostly seen with Maria and in a few cases talking to her in the background.

He has been seen talking or hanging out with other minor characters in the background including some of the fourth graders.

We don't believe it!

Hey, you've told us what Elwood City was like in the past, but what's it like today?

—Alex's other line, "Elwood City Turns 100!"

I need an A in geography.

  • He debuted in the 1993 book D.W. Rides Again! and went on to appear in the Arthur TV series. He was named Alex in the book, then given his surname in "Arthur's First Day."
  • Although he frequently appears in the background throughout the duration of the series, a proper introduction of Alex does not occur until the last one-hour special, "Arthur's First Day." All of his previous speaking roles were one-liners up until this point in the series, but in this special he plays a major role in the main plot.

    In "Arthur's First Day," Arthur mentions that he and Alex have been in the same class for "years". The episode "Brain's Shocking Secret" previously revealed that Alex and Arthur were in the same kindergarten class.
  • He is midfielder for Lakewood Elementary Soccer Team.
  • On the Student of the Month chart, Alex is second last (with Binky being last) which may be a hint that he has a 'trouble-making' personality.
  • His name first appears in the episode "The Scare-Your-Pants-Off Club" on a list that Francine is holding, but he was already off-screen, so the name could not be matched to him until the Student-of-the-Month chart in "MacFrensky."
  • His Glenbrook lookalike, 3rd Grade Male Rat (Number 3), is only recognizable as his lookalike because of the hair.
  • He is seen in the theme song in the show along with Otis, Patrick, Brian and Luke followed by the rest of the main/minor characters.
  • Alex appears to be camera shy as shown in the episode "And Now Let's Talk to Some Kids." He is seen quickly getting up after the cameraman points the camera in his direction.
  • In "Desert Island Dish," he brings what appears to be a bag of oranges for the assignment. This food may be a favorite of his.
  • In "The Boy with His Head in the Clouds," Alex is seen writing down a word problem in math class with great confidence. This could mean that math is a subject that he excels in.
  • In "Arthur's Toy Trouble," he is shown to have a helpful personality when he is helping an elderly woman cross the street. He is wearing a scout uniform.
  • At the time of his appearances in Seasons 1-3, his voice actor, Mitchell Rothpan, was the original voice of George Lundgren.[citation needed]
  • He first speaks in "Buster's Dino Dilemma."
  • Alex is the only kid in Arthur's class to not have an episode titled after him. However, he gets a major role in "Arthur's First Day".
