Passage: Gibson became involved in politics as a member of the Whig Party with strong anti-slavery views. During the U.S. Presidential campaign of 1844, he gave stump speeches for Henry Clay due to the Whig Party's platform that opposed admitting Texas into the Union because it was a slave state. In the U.S. Presidential campaign of 1848, Gibson supported Whig candidate, "Rough and Ready" General Zachary Taylor. However, he was concerned about the Whig Party's lack of opposition to the abolition of slavery and personally visited Henry Clay at his home in Ashland, Kentucky in 1848 to discuss this issue. He lost as a Whig candidate for Ohio Attorney General in 1853. In 1853, following the large defeat of the Whig candidate General Winfield Scott in the U.S. Presidential election of 1852, Gibson threw his support to the Free Soil Party and began organizing what would become the Republican Party in Ohio. He attended the first organization meeting of the Republican Party in spring of 1856 in Pittsburgh. He was one of the 69 Ohio delegates (of a total 600 delegates from around the country) that attended the first Republican National Convention held in Philadelphia in June 1856. In 1856, he ran and was elected as the first Republican to hold the office of Ohio State Treasurer.

Passage: Through his involvement with the Design and Industries Association Holden met Frank Pick, general manager of the Underground Electric Railways Company of London (UERL). Holden at the time had no experience in designing for transport, but this would change through his collaboration with Pick. In 1923, Pick commissioned Holden to design a façade for a side entrance at Westminster Underground station. This was followed in 1924 with an appointment to design the UERL's pavilion for the British Empire Exhibition. Also in 1924, Pick commissioned Holden to design seven new stations in south London for the extension of the City and South London Railway (now part of the Northern line) from Clapham Common to Morden. The designs replaced a set by the UERL's own architect, Stanley Heaps, which Pick had found unsatisfactory. The designs reflect the simple modernist style he was using in France for the war cemeteries; double-height ticket halls are clad in plain Portland stone framing a glazed screen, each adapted to suit the street corner sites of most of the stations. The screens feature the Underground roundel made up in coloured glass panels and are divided by stone columns surmounted by capitals formed as a three-dimensional version of the roundel. Holden also advised Heaps on new façades for a number of the existing stations on the line and produced the design for a new entrance at Bond Street station on the Central London Railway.
