Audrey Russell was a true radio legend of the post-war period. Her voice would have been known to millions while radio was still the senior service. She presented programmes of every kind, from live recordings of the VE Day celebrations to the 1952 Coronation and hundreds of others in between.
On this day in 1964 - early in the space race, when only a handful of humans had orbited the earth - she presented a remarkably prescient discussion on the Third Programme about the risk that humans might contaminate space. Professors of radio astronomy Sir Bernard Lovell and Martin Ryle, meteorologist J.M. Stagg, biologist A Miles and professor of international law R.Y Jennings brought their expertise to the topic.
The programme lasted for an hour and was followed by music for wind instruments by Mozart.
