Irishman McShane was also hampered by the continuing financial constraints, failing to guide Spireites any higher than 12th in his reign. He walked away from football after Chesterfield, retired to Devon and passed away in 2012 aged 81.
McGuigan (pictured on the right) would galvanise the club's fortunes. After a tough start, some astute signings in the 1969-70 season helped Spireites to the top of the table and to their first promotion since 1936, with McGuigan named Manager of the Year. He established the club back in Division Three, before eventually leaving in 1973 for Rotherham. He died in Chesterfield in 1988, aged 64.
Shaw was a playing legend down the road at Sheffield United, as his statue outside Bramall Lane signifies. As manager, he didn't fare so well, as despite occasional glimpses of promise he soon lost the confidence of the players and fans and would depart in 1976. He passed away in 2007 aged 79.
Cox's first managerial job before successful spells at Newcastle and Derby was with Chesterfield. Arriving after a spell as assistant manager with Turkish side Galatasaray, Cox would splash plenty of cash in his time at Saltergate and play attractive football. Promotion, however, just eluded him although things looked promising before Newcastle lured him away. He's now 82-years-old and retired from the game.
