Question:
Stephen McDannell Hillenburg (born August 21, 1961) is an American cartoonist, animator, writer, producer, director, and former marine biologist. He is the creator of the Nickelodeon television series SpongeBob SquarePants (1999-present) which he has also directed, produced, and written. It has gone on to become one of the longest-running American television series as well as the highest-rated show ever to air on Nickelodeon. Born in Lawton, Oklahoma and raised in Anaheim, California, Hillenburg became fascinated with the ocean as a child and also developed an interest in art.
After graduating from college, Hillenburg held various jobs in 1984, including as a park service attendant in Utah and an art director in San Francisco, before landing the job he wanted: teaching children. He hoped to work in a national park on the coast, and eventually found a job at the Orange County Marine Institute (now known as the Ocean Institute), an organization in Dana Point, California that is dedicated to educating the public about marine science and maritime history. Hillenburg was a marine-biology teacher there for three years: "We taught tide-pool ecology, nautical history, diversity and adaptation. Working there, I saw how enamored kids are with undersea life, especially with tide-pool creatures." He stayed at the Dana Point Marina and was also a staff artist. Although "[i]t was a great experience" for him, during this period, Hillenburg realized he was more interested in art than his chosen profession. While working there, he was asked by one of the educational directors if he would be interested in creating an educational comic book about the animal life of tidal pools. He created a comic called The Intertidal Zone, which he used to teach his students. It featured anthropomorphic forms of sea life, many of which would evolve into SpongeBob SquarePants characters--including "Bob the Sponge", the comic's co-host, who resembled an actual sea sponge, as opposed to his later SpongeBob SquarePants character, who resembles a kitchen sponge. He tried to get the comic published, but was turned down by the publishers that he approached. At one point during his tenure with the Orange County Marine Institute, Hillenburg started going to animation festivals such as the International Tournee of Animation and Spike and Mike's Festival of Animation where, at one of those, films made by California Institute of the Arts (colloquially called CalArts) students were shown. He determined that he wanted to pursue a career in that field. Hillenburg had planned to take a master's degree in art, but instead of "going back to school for painting", he left his job in 1987 to become an animator. In 1989, Hillenburg enrolled in the Experimental Animation Program at CalArts. About this decision, he said: "Changing careers like that is scary, but the irony is that animation is a pretty healthy career right now and science education is more of a struggle." He studied under Jules Engel, the founding director of the program, whom he considers his "Art Dad" and mentor. Engel accepted him into the program impressed by The Intertidal Zone. Hillenburg said, "[Engel] also was a painter, so I think he saw my paintings and could easily say, 'Oh, this guy could fit in to this program.' I don't have any [prior experience in] animation really." Hillenburg graduated in 1992, earning a Master of Fine Arts in experimental animation.

Question:
James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
The Civil War erupted within two months of Buchanan's retirement. He supported the United States, writing to former colleagues that "the assault upon Sumter was the commencement of war by the Confederate states, and no alternative was left but to prosecute it with vigor on our part". He also wrote a letter to his fellow Pennsylvania Democrats, urging them to "join the many thousands of brave & patriotic volunteers who are already in the field". Buchanan spent most of his remaining years defending himself from public blame for the Civil War, which was even referred to by some as "Buchanan's War". He began receiving angry and threatening letters daily, and stores displayed Buchanan's likeness with the eyes inked red, a noose drawn around his neck and the word "TRAITOR" written across his forehead. The Senate proposed a resolution of condemnation which ultimately failed, and newspapers accused him of colluding with the Confederacy. His former cabinet members, five of whom had been given jobs in the Lincoln administration, refused to defend Buchanan publicly. Initially so disturbed by the attacks that he fell ill and depressed, Buchanan finally began defending himself in October 1862, in an exchange of letters between himself and Winfield Scott that was published in the National Intelligencer newspaper. He soon began writing his fullest public defense, in the form of his memoir Mr. Buchanan's Administration on the Eve of Rebellion, which was published in 1866. Buchanan caught a cold in May 1868, which quickly worsened due to his advanced age. He died on June 1, 1868, from respiratory failure at the age of 77 at his home at Wheatland and was interred in Woodward Hill Cemetery in Lancaster.
