Problem: Background: Theodor Seuss Geisel ( ( listen); March 2, 1904 - September 24, 1991) was an American author, political cartoonist, poet, animator, book publisher, and artist, best known for authoring more than 60 children's books under the pen name Doctor Seuss (abbreviated Dr. Seuss) (). His work includes several of the most popular children's books of all time, selling over 600 million copies and being translated into more than 20 languages by the time of his death. Geisel adopted the name "Dr. Seuss" as an undergraduate at Dartmouth College and a graduate student at the University of Oxford. He left Oxford in 1927 to begin his career as an illustrator and cartoonist for Vanity Fair, Life, and various other publications.
Context: Geisel's early artwork often employed the shaded texture of pencil drawings or watercolors, but in his children's books of the postwar period, he generally made use of a starker medium--pen and ink--normally using just black, white, and one or two colors. His later books, such as The Lorax, used more colors.  Geisel's style was unique - his figures are often "rounded" and somewhat droopy. This is true, for instance, of the faces of the Grinch and the Cat in the Hat. Almost all his buildings and machinery were devoid of straight lines when they were drawn, even when he was representing real objects. For example, If I Ran the Circus shows a droopy hoisting crane and a droopy steam calliope.  Geisel evidently enjoyed drawing architecturally elaborate objects. His endlessly varied but never rectilinear palaces, ramps, platforms, and free-standing stairways are among his most evocative creations. Geisel also drew complex imaginary machines, such as the Audio-Telly-O-Tally-O-Count, from Dr. Seuss's Sleep Book, or the "most peculiar machine" of Sylvester McMonkey McBean in The Sneetches. Geisel also liked drawing outlandish arrangements of feathers or fur: for example, the 500th hat of Bartholomew Cubbins, the tail of Gertrude McFuzz, and the pet for girls who like to brush and comb, in One Fish, Two Fish, Red Fish, Blue Fish.  Geisel's illustrations often convey motion vividly. He was fond of a sort of "voila" gesture in which the hand flips outward and the fingers spread slightly backward with the thumb up. This motion is done by Ish in One Fish, Two Fish, Red Fish, Blue Fish when he creates fish (who perform the gesture with their fins), in the introduction of the various acts of If I Ran the Circus, and in the introduction of the "Little Cats" in The Cat in the Hat Comes Back. He was also fond of drawing hands with interlocked fingers, making it look as though his characters were twiddling their thumbs.  Geisel also follows the cartoon tradition of showing motion with lines, like in the sweeping lines that accompany Sneelock's final dive in If I Ran the Circus. Cartoon lines are also used to illustrate the action of the senses--sight, smell, and hearing--in The Big Brag, and lines even illustrate "thought", as in the moment when the Grinch conceives his awful plan to ruin Christmas.
Question: was he trained in art?
Answer: Geisel evidently enjoyed drawing architecturally elaborate objects.

Problem: Background: Lisa Marie Simpson is a fictional character in the animated television series The Simpsons. She is the middle child and most intelligent of the Simpson family. Voiced by Yeardley Smith, Lisa was born as a character in The Tracey Ullman Show short "Good Night" on April 19, 1987. Cartoonist Matt Groening created and designed her while waiting to meet James L. Brooks.
Context: In The Tracey Ullman Show shorts, Lisa was something of a "female Bart": equally mischievous but lacking unique traits. As the series progressed, Lisa began to develop into a more intelligent and more emotional character. She demonstrates her intellect in the 1990 episode "Krusty Gets Busted" (season one), by helping Bart reveal Sideshow Bob's plot to frame Krusty the Clown for armed robbery. Many episodes focusing on Lisa have an emotional nature, such as "Moaning Lisa" (season one, 1990). The idea for the episode was pitched by James L. Brooks, who wanted to do an emotional episode involving Lisa's sadness, to complement the many "jokey episodes" in the first season.  In the seventh-season episode "Lisa the Vegetarian" (1995), Lisa permanently becomes a vegetarian, distinguishing her as one of the first primetime television characters to make such a choice. The episode was written by David S. Cohen (in his first solo writing credit) who jotted down the idea one day while eating lunch. Then-executive producer David Mirkin, who had recently become a vegetarian, quickly approved the idea. Several of Lisa's experiences in the episode are based on Mirkin's own experiences. The episode guest stars musician Paul McCartney, a committed vegetarian and animal rights activist. McCartney's condition for appearing was that Lisa would remain a vegetarian for the rest of the series and would not revert the next week (as is common on situation comedies). The trait stayed and is one of the few permanent character changes made in the show. In the season 13 episode "She of Little Faith" (2001), Lisa underwent another permanent character change when she converted to Buddhism.  Lisa plays the baritone saxophone, and some episodes use that as a plot device. According to Matt Groening, the baritone saxophone was chosen because he found the thought of an eight-year-old girl playing it amusing. He added, "But she doesn't always play a baritone sax because the animators don't know what it looks like, so it changes shape and color from show to show." One of the hallmarks of the show's opening sequence is a brief solo Lisa plays on her saxophone after being thrown out of music class. The Simpsons composer Alf Clausen said that the session musicians who perform her solos do not try to play at the second grade level and instead "think of Lisa as a really good player."
