The Cambridge Circus or Keynes's Circus was a group of young Cambridge economists closely associated with John Maynard Keynes. The group consisted of Richard Kahn, James Meade, Joan Robinson, Austin Robinson, and Piero Sraffa. The Circus formed immediately following the 31 October 1930 publication of Keynes's A Treatise on Money. The group met to read and discuss the Treatise and to provide feedback on Keynes's continuing theoretical work that would lead to his General Theory of Employment, Interest, and Money. Sraffa initiated the group, which met in Kahn's rooms of the Gibb's Building at King's College. The Circus met among themselves and in a seminar, which included some undergraduates, during the 1930-1931 academic year. The seminar convened in the Old Combination Room of Trinity Colle
