Nigel Charles Ratburn (formerly Emil Ratburn) is a third grade teacher at Lakewood Elementary School. In "Mr. Ratburn and the Special Someone," Mr. Ratburn married a chocolate shop owner named Patrick.
As a baby, Mr. Ratburn wore a light blue sweater with a white collar, a red bowtie, white cloth diapers with pins, bright red shoes and blue socks. At the age of one or two, he was already able to write multiplication problems.
As a kid, he had three outfits. Two of them were the Glenbrook Academy's uniforms. Then, he had casual clothes that he wore to events, like the Father's Day picnic. They consisted of a blue buttoned shirt with a white shirt under it and blue pants.
In the episode "Arthur Weighs In," it’s revealed that as a child he used to be overweight (a "fatty rat" as he put it when talking with Arthur) until he began exercising more while learning to play ping-pong.
As a teenager, he attended Elwood City High School with Bailey, David Read and Mr. Haney. In "Arthur's Almost Boring Day," it’s revealed that he was a member of the Elwood City High School football team.
Mr. Ratburn announces that he’ll become a fourth grade teacher during the upcoming school year in "The Last Day." Besides this, not much is known about Mr. Ratburn's future outside of what is depicted in dream sequences. During the futuristic scene in the episode, "Buster Makes the Grade," it’s suggested that Mr. Ratburn will continue his career as a teacher at Lakewood Elementary for many years to come.
In Arthur's dream in "D.W. and the Beastly Birthday," Mr. Ratburn is seen four years in the future, with a goatee and glasses. He wears a black suit with a green turtleneck sweater.
Mr. Ratburn's appearance consists of a green suit complete with a solid yellow shirt and bright red necktie (in the books, his uniform ranges to different colors). Being a rat, he has long whiskers, which he appears to keep trimmed.
He has brown clumps of hair in the books; although, in the cartoon show, his hair was restricted to thin black lines. He also wears his shirts tucked into his pants and always wears a belt buckle with his pants. He also wears blue pajamas, and in one episode, he wore a turquoise night shirt, and in another episode, he also wore a tan colored sweater and black pants and brown or black slippers.
His casual clothing consists of a cream-colored T-shirt and faded blue jeans. For formal occasions, Mr. Ratburn wears a charcoal or black Tuxedo jacket with a white tuxedo shirt black bow tie and charcoal or black tuxedo trousers.
When outdoors for something like fossil-hunting, Mr. Ratburn wears a dark brown hat with a yellow line on the bottom of the tip of the hat going all around the tip. He also wears a very light yellow or beige shirt and a dark blue scarf tucked into the shirt.
He also has a short-sleeved beige jacket with two pockets one on each side of the jacket and two shoulder straps, one on each side of the jacket. He also wears blue shorts, very light yellow or beige socks, and light brown boots. He always carries a briefcase with him to class.
Mr. Ratburn is primarily known for being a strict teacher, but he has many other hobbies outside of the classroom, including puppetry, playing in a rock band, and bird-watching. He’s also seen as a role model by several students. For instance, he encourages Arthur to be more physically active in "Arthur Weighs In," and he’s able to relate to Maria's stuttering problem in "Maria Speaks."
He tends to give a lot of homework, projects and tests to the students in his class, which leads many to believe that he’s the toughest teacher at Lakewood Elementary School. Despite the heavy amount of school work to do, many of his students come to find out he isn’t as bad as they initially thought after he explains about organization, self-discipline and how they can do their homework and have time for things that they like to do. Arthur, Buster and Brain consider Mr. Ratburn their friend and Arthur says hi to him when he sees him in public.
Even though Mr. Ratburn is calm and cool, he cackles uncontrollably in the dream sequences that the other characters have involving him in.
Mr. Ratburn is often friendly, helpful and good-natured, rarely showing any hint of malice and has shown that he truly cares about his students time and time again. In "The Last Day" and the song "Pop Quiz from Ratburn," Mr. Ratburn explains that his schoolwork is difficult because he wants to challenge his students and knows they can handle it. Mr. Ratburn takes his role as a teacher seriously and often tries to mentor his students, occasionally in non-academic fields. When the roof of his house collapses, Mr. Ratburn stays with the Read family, and is shown to enjoy watching Spooky Poo and other fun things, to Arthur's surprise.
He frequently struggles with new, modern technology, such as using computers, the Internet and his classroom's new interactive "smart" board; for example, the first time he used the Internet, he fell for multiple scams. This may be why he often uses an old film projector during his class lessons. He does become a bit more acclimated to some technology in various situations, however. He learns to use a tablet device called the BoysenBerry and he manages to purchase a canoe online in "Best of the Nest."
