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.

Steve "Slug" Russell is a programmer and computer scientist most famous for creating Spacewar!, one of the earliest videogames, in 1961 with the fellow members of the Tech Model Railroad Club at MIT working on a DEC Digital PDP-1. While there is some debate over priority regarding the concept of computer-based games in general, Spacewar! was unquestionably the first to gain widespread recognition, and is generally recognized as the first of the "shoot-'em' up" genre.

Steve Russell wrote the first two implementations of Lisp for the IBM 704. It was Russell who realized that the concept of universal functions could be applied to the language; by implementing the Lisp universal evaluator in a lower-level language, it became possible to create the Lisp interpreter (previous development work on the language had focused on compiling the language). He invented the continuation to solve a double recursion problem for one of the users of his Lisp implementation.

Steve Russell is an alumn of Dartmouth College and the Massachusetts Institute of Technology.
