"Colonel" George Fabyan (March 15, 1867 – May 17, 1936) was an American businessman who founded a private research laboratory.

Illinois Governor Richard Yates Jr. appointed Fabyan to his military guard in 1901, giving him the honorary title of Colonel, by which he was later known.

He was appointed as a liaison to General Kuroki Tamemoto during the Russo-Japanese peace negotiations (Treaty of Portsmouth) held in Maine in 1905.

They lived on their estate from 1908 to 1939 in a farmhouse remodeled by Frank Lloyd Wright, which they called the Fabyan Villa.

[4] In 1914 Fabyan purchased and had moved a Dutch-style windmill built c. 1870 from its original farm site in York Center, Illinois to his estate.

[5] Fabyan supported the Baconian theory, which was popular at the time, that Shakespeare's plays were written by Francis Bacon.

[9] Selig was intending to capitalise on the celebrations organised for the upcoming 300th anniversary of Shakespeare's death, which occurred in April 1616.

[10] In the ensuing uproar, Tuthill rescinded his decision on 2 May 1916,[11] and another judge, Frederick A. Smith, dismissed the ruling on 21 July 1916.

[17] Decades after working for Fabyan, William and Elizebeth collaborated on a study to discredit the ciphers that Gallup claimed to have discovered.
