Vale Roger Estall

My dear friend, mentor, collaborator and co-author Roger died suddenly and unexpectedly on Wednesday 21 June 2023.

Roger was visiting the city he was born, Christchurch in New Zealand, with his partner.

Roger’s passing leaves a big hole in the world. It is said that he saved more lives in New Zealand than anyone else through his dogged pursuit of smoke alarms and fire sprinkler systems.

I’d like to recognise the wisdom and friendship he gifted me over many years. He taught me never to compromise on logic and to challenge anything that, quite simply, did not make sense. A trait I know he helped many others develop.

We can only aspire to make the positive impact on mankind that Roger achieved.

Rest In Peace my dear friend, you will be missed for ever.
