This volume contains the correspondence between G.L.S. Shackle and S.F. Frowen from the time Shackle took up his first post-war academic appointment until his death in 1992. The correspondence, partly personal and partly professional, reveals a vital insight into Shackle both as a man and as an outstanding economist. His letters illuminate his thoughts on issues occupying his mind but also show the warmth and tremendous generosity he felt towards his friends. The centenary of Shackle's birth in 2003 seems an appropriate time for the publication of his letters.
