Q: Question: Did Potter attend school in the same county? Passage:Potter was born in Bedford to Reverend Brignal Peel, a Wesleyan minister, and Elizabeth Stimson. He was educated at Bedford Modern School and for a time at Worcester College, Oxford. He first performed in E. M. Royle's The White Man at the Lyric Theatre in London before touring.

He served in the 6th Division 2nd Brigade 21st Battery, from 8 February 1917 before returning to music hall once the war was over. Potter cultivated an individual style and persona, wearing a straw boater, wide grey flannel trousers (he said he invented the Oxford bags style at the Coliseum in 1920), an 'Old Borstolian' blazer and carrying a notebook with a rolled umbrella. James Agate described him as "that sham Harrovian who bears upon his blazer the broad arrows of a blameful life".

Q: Question: What year did the magazine that Jones father worked for begin publication? Passage:Carroll Nathaniel Jones III (July 2, 1944 - June 22, 2017) was an artist in the style of American realism. Carroll grew up in New Providence, New Jersey where his father, an illustrator for Life (magazine), was his first art teacher. He taught Carroll techniques of the Old Masters, who emphasized light, perspective, and composition. Carroll went to school in New York City (NYC) and enrolled in the Phoenix School of Design at age 17. He later attended Hartford Art School and became a commissioned portraitist for 10 years. His work, Church Window was recognized in the New York Times, and he moved away from portraits to recreate scenes that sparked memories of his childhood. He was most influenced by Andrew Wyeth and Edward Hopper. The Coe-Kerr Gallery of NYC and Whistler's Daughter Gallery of New Jersey represented him, as well as contemporaries Wyeth and Hopper. Malcolm Forbes, Frederick R. Koch, Stephen Sondheim, William Schuman, and Jean Shepherd held private collections of his work. He exhibited at Newark Museum and Trenton Art Museum in New Jersey, and in universities, galleries and museums in seven states by his mid-thirties. His work is part of the permanent collections of Seton Hall University and Newark Museum. Art critic Marion Filler considered his work Magic realism, a quiet movement made popular in America beginning in the 1920s by Hopper, and related to Surrealism.
