Joseph Mason "Bull" Reeves was an admiral in the United States Navy and an early and important supporter of U.S. Naval Aviation. Though a battleship officer during his early career, he became known as the "Father of Carrier Aviation" for his role in integrating aircraft carriers into the fleet as a major part of the Navy's attack capabilities.

A football helmet is a type of protective headgear used mainly in gridiron football, although a structural variation has occasional use in Australian rules football. It consists of a hard plastic shell with thick padding on the inside, a face mask made of one or more plastic-coated metal bars, and a chinstrap. Each position has a different type of face mask to balance protection and visibility, and some players add polycarbonate visors to their helmets, which are used to protect their eyes from glare and impacts. Helmets are a requirement at all levels of organized football, except for non-tackle variations such as flag football. Although they are protective, players can and do still suffer head injuries such as concussions.
