Passage: Doubleday's invention of baseball was the finding of a panel appointed by Albert Spalding, a former star pitcher and club executive, who had become the leading American sporting goods entrepreneur and sports publisher. Debate on baseball's origins had raged for decades, heating up in the first years of the 20th century, due in part to a 1903 essay baseball historian Henry Chadwick wrote in Spalding's Official Baseball Guide stating that baseball gradually evolved from English game of "rounders". To end argument, speculation, and innuendo, Spalding organized the Mills Commission in 1905. The members were baseball figures, not historians: Spalding's friend Abraham G. Mills, a former National League president; two United States Senators, former NL president Morgan Bulkeley and former Washington club president Arthur Gorman; former NL president and lifelong secretary-treasurer Nick Young; two other star players turned sporting goods entrepreneurs (George Wright and Alfred Reach); and AAU president James E. Sullivan.
