Donald Robertson (writer)

Donald Robertson (22 August 1930 – 5 September 1995) was a Scottish engineer turned scriptwriter who penned four episodes of Thunderbirds: "Edge of Impact", "Desperate Intruder", "Danger at Ocean Deep" and "Path of Destruction". Usually his stories revolved around machines and vehicles in peril.

Robertson wrote his scripts in a caravan parked at the end of his garden in Birmingham, finding it peaceful and quiet. His other TV work seemingly included Dr. Finlay's Casebook and Crossroads.

From the 1960s until his death, Robertson owned and managed Quill Productions. Originally a scriptwriting company, it went on to produce in-house training videos and corporate videos for big-name giants such as JCB, British Gas and Jaguar.
