Encounters with the Doctor
The Fourth Doctor claimed to have met Einstein. (TV: The Stones of Blood)

In the 1940s, the Rani kidnapped Einstein and brought him to Lakertya so that his genius could be used to help create her time brain. Afterwards, the Seventh Doctor boarded him on his TARDIS in order to bring him back to his right time; the curiosity of the scientist was aroused by the console room. (TV: Time and the Rani)

The Eighth Doctor mentioned knowing Einstein. (PROSE: The Eye of the Tyger)

The Eleventh Doctor once claimed to have attended a party at Frank Sinatra's hunting lodge with Einstein and Father Christmas. He produced a photograph of them as proof. (TV: A Christmas Carol)

Other encounters between Einstein and the Doctor included Einstein trying to steal the Doctor's TARDIS and having his toothbrush taken by the Doctor and "exterminated" by the Daleks. Einstein also left his bicarbonated processing machine somewhere in the TARDIS.

While working on a malfunctioning time machine of his own in 1945, Einstein was accidentally brought onboard the TARDIS in an accident involving the TARDIS console and the Doctor's new fez (which Einstein had been the original owner of) along with his fez and a flask of experimental liquid which he hoped was bionic fusion liquid. Einstein was momentarily transformed into an Ood by his liquid, before being changed back and returned home by the Doctor; the mishap had resulted in Einstein's hair standing on end, a look which the Doctor recommended he keep as "more sciencey".
