Sir Henry Cole (15 July 1808 – 18 April 1882) was an English civil servant and inventor who facilitated many innovations in commerce and education in 19th century Britain. Cole is credited with devising the concept of sending greetings cards at Christmas time, introducing the world's first commercial Christmas card in 1843.

Henry Cole was born in Bath, and educated at Christ's Hospital in London. He began his career at the age of 15 at the Public Record Office, where he became Assistant Keeper and was instrumental in reforming the organisation and preservation of the British national archives.

From 1837 to 1840, he worked as an assistant to Rowland Hill and played a key role in the introduction of the Penny Post. He is sometimes credited with the design of the world's first postage stamp, the Penny Black.^{[citation needed]}

In 1843, Cole introduced the world's first commercial Christmas card, commissioning artist John Callcott Horsley to make the artwork.

Cole was personally interested in industrial design, and under the pseudonym Felix Summerly designed a number of items which went into production, including a prize-winning teapot manufactured by Minton. As Felix Summerly, he also wrote a series of children's books, including A book of stories from The home treasury; A hand-book for the architecture, sculpture, tombs, and decorations of Westminster Abbey (1859); An Alphabet of Quadrupeds (1844); and The most delectable history of Reynard the Fox (illustrated with twenty-four coloured pictures by Aldert van Everdingen) (1846).

David Howell Evans (born 8 August 1961), more widely known by his stage name The Edge (or just Edge), is a musician best known as the guitarist, backing vocalist, and keyboardist of the Irish rock band U2. A member of the group since its inception, he has recorded 12 studio albums with the band and has released one solo record. As a guitarist, The Edge has crafted a minimalistic and textural style of playing. His use of a rhythmic delay effect yields a distinctive ambient, chiming sound that has become a signature of U2's music.

The Edge was born in England to a Welsh family, but was raised in Ireland after moving there as an infant. In 1976, at Mount Temple Comprehensive School, he formed U2 with his fellow students and his older brother Dik. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most popular acts in popular music, with successful albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, The Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, The Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally contributed lyrics. The Edge met his second and current wife, Morleigh Steinberg, through her collaborations with the band.

Joseph L. "Joe" Sanders (October 15, 1896, Thayer, Kansas - May 14, 1965, Kansas City, Missouri) was an American jazz pianist, singer, and bandleader associated with Kansas City jazz for most of his career.

Sanders was best known for co-leading the Coon-Sanders' Nighthawks along with Carleton Coon (1894–1932). The pair formed the group in 1920 in Kansas City under the name Coon-Sanders Novelty Orchestra, broadcast for the first time on radio the following year, and became known as the Nighthawks because of their frequent appearances on late-night radio. They recorded in Chicago in 1924 and held a residency at the Blackhawk club in that city from 1926. The ensemble toured as a Midwestern territory band, and after Coon's death Sanders continued to lead the band under his own name.

Sanders worked mostly in Hollywood studios in the 1940s, and occasionally led performances at the Blackhawk once again. He was a vocalist for the Kansas City Opera in the 1950s.
