William Joseph ("Wild Bill") Donovan (January 1, 1883 – February 8, 1959) was an American soldier, lawyer, intelligence officer and diplomat.
 Donovan is best remembered as the wartime head of the Office of Strategic Services (OSS), the precursor to the Central Intelligence Agency, during World War II.
 He is also known as the "Father of American Intelligence" and the "Father of Central Intelligence".
 "The Central Intelligence Agency regards Donovan as its founding father," according to journalist Evan Thomas in a 2011 "Vanity Fair" profile.
 The lobby of CIA headquarters, in Langley, Virginia, now features a statue of Donovan.
 Thomas observed that Donovan's "exploits are utterly improbable but by now well documented in declassified wartime records that portray a brave, noble, headlong, gleeful, sometimes outrageous pursuit of action and skulduggery."

 It measures 49 m (54 yds) in width at its southern end, 46 m (50 yds) at the north, and is 500 m (547 yds) in length.
 During the 17th century it was a narrow street known as Drogheda Street (named after Henry Moore, Earl of Drogheda).
 It was widened, and renamed 'Sackville Street' (named after Lionel Sackville, 1st Duke of Dorset) in the late 1700s until 1924, when it was renamed in honour of Daniel O'Connell, a nationalist leader of the early 19th century, whose statue stands at the lower end of the street, facing O'Connell Bridge.
Master Scuba Diver (MSD) is a scuba diving certification or recognition level offered by several North American diver training agencies, such as the National Association of Underwater Instructors (NAUI), the Professional Association of Diving Instructors (PADI), Scuba Diving International (SDI), and Scuba Schools International (SSI).

 Each of these (and other) agencies touts their program at this level as the highest, non-leadership program.
John Pitts Spence (June 14, 1918 – October 29, 2013) was an American diver for the United States Navy and World War II veteran who is widely credited as the country's first combat frogman.
