To develop the character, the producers sought the assistance of Jamake Highwater.

Question: How old was the manager who took Port Vale FC to their second Third Division North title in 1953-54? Passage 1:On 26 July 1830, the revolution of the so-called Three Glorious Day (or July Revolution) erupted due to the authoritarian and anti-Gallican tendencies showed by Charles X and his Prime Minister Jules de Polignac, expressed by the recently approved Saint-Cloud Ordinances. Despite the abdication of Charles X and the Dauphin Louis in favor to Charles X's grandson Henri, Duke of Bordeaux, on 2 August 1830, only seven days later Louis Philippe I, still Duke of Orléans, was elected by the Chamber of Deputies as new "King of the French". The enthronement of Louis Philippe was strongly wanted by Doctrinaires, the liberal opposition to Charles X's ministries, under the concept "nationalize the monarchy and royalize France". On 14 August 1830, the Chamber approved a new Constitution, who became the de facto political manifesto for the Orléanists, containing the basis for a constitutional monarchy with a central Parliament. The Orléanism, became the dominant tendency within political life, easily divided inside the Chamber of Deputies between the centre-left of Adolphe Thiers and the centre-right of François Guizot. Louis Philippe showed himself more aligned with Guizot, entrusted to the higher offices of government, and rapidly became associated with the rising "new men" of the banks, industries and finance, gaining the epithet of "Roi bourgeois". In the early 1840s, Louis Philippe's popularity decreased, due to his strong connection to upper classes and repression against workers' strikes, and showed few concerns for his weakened position, leading the writer Victor Hugo to describe him as "a men with many little qualities". The Orléanist regime finally fell in 1848, when a revolution erupted and on 24 February Louis Philippe abdicated in favor to his grandson Philippe, Count of Paris, under regency of his mother Helene, Duchess of Orléans, who was quickly ousted out from the Chamber of Deputies during the regency's formalization, who was interrupted by republican deputies who instead proclaimed the Second Republic.
 Passage 2:In 1851, she met Elizabeth Cady Stanton, who became her lifelong friend and co-worker in social reform activities, primarily in the field of women's rights. In 1852, they founded the New York Women's State Temperance Society after Anthony was prevented from speaking at a temperance conference because she was female. In 1863, they founded the Women's Loyal National League, which conducted the largest petition drive in United States history up to that time, collecting nearly 400,000 signatures in support of the abolition of slavery. In 1866, they initiated the American Equal Rights Association, which campaigned for equal rights for both women and African Americans. In 1868, they began publishing a women's rights newspaper called The Revolution. In 1869, they founded the National Woman Suffrage Association as part of a split in the women's movement. In 1890, the split was formally healed when their organization merged with the rival American Woman Suffrage Association to form the National American Woman Suffrage Association, with Anthony as its key force. In 1876, Anthony and Stanton began working with Matilda Joslyn Gage on what eventually grew into the six-volume History of Woman Suffrage. The interests of Anthony and Stanton diverged somewhat in later years, but the two remained close friends.
 Passage 3:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 1953–54. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 1958–59. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.
