Michael Lachmann obituary

Television documentary producer and director who collaborated with Brian Cox on Wonders of the Solar System

The television producer and director Michael Lachmann, who has died aged 54 in a mountaineering accident in the French Alps, helped to turn the former pop musician and particle physics professor Brian Cox into a TV presenter known for bringing science documentaries into a new age. Lachmann also took the pig farmer Jimmy Doherty around the world to explore the pros and cons of GM foods, and made thought-provoking programmes on great scientists and the space race.

His skill in popularising science without dumbing down included placing Cox inside a derelict Rio de Janeiro jail for a sequence in the 2011 BBC Two series Wonders of the Universe. Cox sprayed chemical element symbols on the walls, and Lachmann had the building dramatically blown up. The four-part series attempted to answer the question: What are we and where do we come from?" In Stardust, the episode directed by Lachmann, he and Cox travelled not only to Brazil, but also to Kathmandu and Chile, to reveal the origins of humans in distant stars.
