First-half goals from Kristian Dennis and Jordan Sinnott gave the Spireites their first win of the season as they beat Port Vale 2-0 at the Proact.
Tommy Lee returned in goal following his long injury lay-off while Jordan Flores made his debut after signing on loan from Wigan Athletic.
The Spireites could have taken an early lead seven minutes in when Dennis found himself through on goal but dragged his shot wide.
A minute later, both sets of fans rose to their feet to applaud Chesterfield legend Ernie Moss, who is suffering from a form of dementia.
There was a scare for Chesterfield when Ian Evatt went close to heading into his own net with Lee touching it wide for a corner.
A good move down the right-hand side led to Ben Whitfield having his shot well blocked by Sam Hird.
Marcus Harness, who was a menace throughout the first half, charged into the box and his low driven shot across the goal was met by Dan Turner, whose touch could only send the ball trickling past the post.
The Spireites then enjoy the better of the play and it eventually paid off as they took the lead through Dennis (38), who slotted the ball home after being put through by Sinnott.
Then, just two minutes before the half-time whistle, it was Sinnott’s turn to get on the score sheet. Sinnott rattled the bar with a thunderous shot and Dennis slipped the loose ball to Flores, who forced a good save from Hornby and Sinnott followed up to fire home.
Vale nearly got one back four minutes after the break when Michael Tonge fired a free kick from 25 yards just past Lee’s near post.
Ten minutes, later Dennis led a lightning fast counter attack. After he was tackled the ball fell to Sinnott who drove forward before trying to set up O’Grady, but a heroic sliding tackle from Nathan Smith forced the ball out of play.
In the 76th minute, Vale had another opportunity to score when a momentary lapse in the Spireites defence allowed substitute Anthony De-Freitas space, but he dragged his shot wide.
Two minutes later O’Grady, had a chance on the back of another counter attack. Led by Flores down the left, the ball found its way via Dennis to O’Grady eight yards out and he fired wide.
The only time Lee was seriously threatened was when Tom Pope had a clear header from a corner six yards which was saved on the line and Scott Wiseman cleared.
