The new exhibition will include some of Sir Nigel’s letters and hand-written notes, along with artefacts including his hat and passport, organisers said.
One of the lesser-known people to work closely with Sir Nigel was Doncaster man Harry Harper.
As his personal assistant, Mr Harper was entrusted with Sir Nigel’s personal notebooks and papers which are a central part of the exhibition.
Philip Benham, chairman of the Gresley Society said: “One hundred years on from the event that first thrust the world’s most famous locomotive into the limelight, it is fitting to see the achievements of Flying Scotsman’s creator commemorated in this wonderful exhibition.
“It is all the more appropriate that it is being held in Doncaster, where so many of Gresley’s achievements took place.”
