Lazarus Laboratories

Lazarus Laboratories were the laboratories of Richard Lazarus. His research was funded by Harold Saxon, and Lazarus Laboratories's logo was very similar to the insignia on the Master's ring. The Tenth Doctor and Martha Jones attended a reception there, when Professor Lazarus was showing his machine. (TV: The Lazarus Experiment)

The Lazarus Labs were located in Southwark. Richard Lazarus tested his hypotheses on age-reversal there. He also hosted a party to show people his inventions. (TV: The Lazarus Experiment)
