Tactical Studies Rules

Tactical Studies Rules (1973–1975)

Tactical Studies Rules (TSR) was formed in 1973 as a partnership between Gary Gygax and Don Kaye, who collected together $2,400 for costs related to startup, to formally publish and sell the rules of Dungeons & Dragons, the creation of Gygax and Dave Arneson and the first modern role-playing game (RPG). The first TSR release, however, was Cavaliers and Roundheads, a miniature game, to start generating income for TSR. The partnership was subsequently joined by Brian Blume in December 1973. Blume was admitted to the partnership to fund further publishing of D&D, as Cavaliers and Roundheads was not a commercial success. In the original configuration of the partnership, Kaye served as president, Blume as vice-president, and Gygax as editor.
