Entdecker (German: "Discoverer") is a German-style board game designed by Klaus Teuber and published in 1996 by Goldsieber in German.
 Although the game won 2nd prize in the Deutscher Spiele Preis, many gamers were disappointed with the game after the success of Teuber's previous game, "The Settlers of Catan".
 An updated version, "Die Neuen Entdecker", was published in 2001 by Kosmos; this version was published in English by Mayfair Games under the title "Entdecker - Exploring New Horizons".
 This version of the game won the Essen Feather for that year.

 'Bob' Leavitt was also the longtime historian of the original Baker Street Irregulars, devoted to all things Holmesian, about which he wrote in his "The Origins of 221B Worship."

A statue of Sherlock Holmes by the sculptor John Doubleday stands near the supposed site of 221B Baker Street, the fictional detective's address in London.
 Unveiled on 23 September 1999, the sculpture was funded by the Abbey National building society, whose headquarters were on the purported site of the famous address.
 As no site was available on Baker Street itself the statue was installed outside Baker Street tube station, on Marylebone Road.
 Doubleday had previously produced a statue of Holmes for the town of Meiringen in Switzerland, below the Reichenbach Falls whence the detective fell to his apparent death in the story "The Final Problem".
