Nikos Spiridakis
From Tardis Wiki, the free Doctor Who reference
Nikos Spiridakis was a Greek seismologist who worked with Professor Katsoudas some time in the 1950s.
Spiridakis was a young man when he met the Third Doctor and Jo Grant, but all the hair on his body was white instead of black. Jo found Spiridakis attractive.
When the Doctor and Jo accompanied Spiridakis and Katsoudas to their dig site, Spiridakis and Jo took the lift underground. Katsoudas started an earthquake, trapping Jo and injuring Spiridakis.
Spiridakis was being hypnotised by Katsoudas, but fought it to help rescue Jo from the Master and stop his plans. However, the Master's device aged Spiridakis to death before the Doctor could get him to the TARDIS. (PROSE: The Seismologist's Story)
