Bert Hawthorne

He was born in Derryhennett, County Armagh, Northern Ireland and immigrated to New Zealand at 13 years of age.

He moved to the United Kingdom to work as a racing mechanic at Ron Tauranac's Brabham factory.

He built a Brabham BT21 and shipped it back to New Zealand where he raced it in the National Formula category for twin-cam, 1600 cm3 engines.

Hawthorne was killed on 14 April 1972, during practice for the following round of the European Championship, the Jim Clark Memorial Race at Hockenheim.

At the track it was realised that both Terbeck and Hawthorne were missing, but there was no knowledge of the incident until two laps later, when Niki Lauda pulled in to the pits and asked why nothing was being done about a car on fire on the circuit.
