Some context: David was born on 28 January 1858, in St. Fagans near Cardiff, Wales, the eldest son of the Rev. William David, a fellow of Jesus College, Oxford, a classical scholar and naturalist and his wife Margaret Harriette (nee Thomson). His mother's cousin, William A. E. Ussher of the Geological Survey, first interested David in what was to be his life work. At the age of 12, David went to Magdalen College School, Oxford in 1870. In 1876 he gained a classical scholarship to New College, Oxford.
In 1896 the Davids bought 26 acres (10.5 hectares) at Woodford, in the Blue Mountains, with an existing weatherboard cottage, two-roomed with two skillion rooms at the back. To emphasise his Welsh origins, Edgeworth David named the Woodford cottage 'Tyn-y-Coed', the 'house in the trees' (often mistranslated as 'the shack in the bush': 'ty' is a proper house in Welsh, not a mere hut).  In 1915 the Davids offered their home to the Red Cross convalescent home for the rehabilitation of injured servicemen and the Woodford Academy boys erected a flagstaff for the Union Jack and Red Cross flags for the soldiers in residence. When the Cooee marchers trooped past in November 1915 some of the wounded soldiers were brought up to the main road to greet the marchers. Although they had work and commitments in Sydney, Woodford was the David's primary residence from 1899 until 1920. They retained the Woodford cottage as a favoured country retreat until Edgeworth's death in 1934. Tyn-y-Coed was destroyed by bushfire in 1944 with only a chimney stump remaining. Its grounds are now occupied by eight modern houses, their gardens and adjoining bush.  In September 1920, David was created a Knight Commander of the Order of the British Empire for services during the war.  Returning to Australia, David purchased Coringah, a cottage in the Sydney suburb of Hornsby. He also took up a long-cherished project, the writing of a definitive work, The Geology of the Commonwealth of Australia. In 1921-22 David helped set up the Australian National Research Council and served as its first President. In 1924 he retired as Professor of Geology at the University of Sydney, the chair passing to his student Leo Cotton, a neighbour in Hornsby, New South Wales, whose brother Max Cotton created Lisgar Gardens in Hornsby. In 1928 he discovered what he believed were Precambrian fossils, creating controversy which remained until his death.  In 1931 he published the Geological Map of the Commonwealth and the accompanying Explanatory Notes, designed to be part of his Geology of the Commonwealth of Australia. He died in 1934 without being able to complete this work and was given a state funeral.

Some context: Povenmire was born in San Diego, California on September 18, 1963, and grew up in the city of Mobile, Alabama. A child prodigy, he began drawing at age two; by the time he was ten, his work was displayed in local art shows. His first efforts in animation included a series of flip books that he produced in his school text books. As a child, Povenmire considered animator Chuck Jones his hero; in a 2009 interview, he stated that "every drawing he [Jones] did was beautiful to look at and had so much energy in it".
In 1993, Povenmire and Marsh conceived the series Phineas and Ferb, based on their similar experiences of childhood summers spent outdoors. Povenmire spent 14-16 years pitching Phineas and Ferb to several networks. Most rejected it as unfeasible for the complexity of its plots, but Povenmire persevered, later observing "It was really the show we wanted to see: if this was on the air, I'd watch it, and I don't always feel that about every show I work on." Even the Walt Disney Company initially rejected Povenmire's pitch, but asked to keep the proposal packet: "Usually that means they throw it in the trash later," Povenmire recalled. Eventually Disney called Povenmire back with an acceptance, on the condition that he would produce an 11-minute pilot. He called Marsh, who was living in England, to ask him if he would like to work on the pilot; Marsh accepted immediately and moved back to the United States.  Instead of a conventional script, the pair pitched the pilot by recording reels of its storyboard, which Povenmire then mixed and dubbed to produce action and vocals. The network approved the show for a 26-episode season. Povenmire left Family Guy to create the series.  Povenmire and Marsh wanted to incorporate into Phineas and Ferb the kind of humor they had developed in their work on Rocko's Modern Life. They included action sequences and, with Disney's encouragement, featured musical numbers in every episode subsequent to "Flop Starz". Povenmire described the songs as his and Marsh's "jab at immortality", but the pair have earned two Emmy nominations for Phineas and Ferb songs to-date. A third Emmy nomination, for the episode "The Monster of Phineas-n-Ferbenstein" (2008), pitted the show against SpongeBob SquarePants, although neither nominee received the award due to a technicality. In 2010, Povenmire was nominated amongst several other Phineas and Ferb crew members for the Daytime Emmy Award for both "Outstanding Writing in Animation" and "Outstanding Original Song - Children's and Animation" for their work on the show, winning for "Outstanding Writing in Animation".  The distinctive style of the animation legend Tex Avery influenced the show's artistic look. Like Avery, Povermire employed geometric shapes to build both the characters and the background. The style developed almost accidentally, with Povenmire's first sketch of title character, Phineas Flynn, which he produced while eating dinner with his family in a restaurant in South Pasadena, California. He doodled a triangle-shaped child on the butcher paper covering the table. He was so taken with sketch he tore it out, kept it, and used it as the prototype for Phineas and as the stylistic blueprint for the entire show.
