Martha Jones is a fictional character played by Freema Agyeman in the
long-running British science fiction television series Doctor Who and
its spin-off series, Torchwood. She is a companion of the Tenth Doctor
in Doctor Who, after Rose Tyler (Billie Piper) and before Donna Noble
(Catherine Tate). According to the character's creator and executive
producer Russell T Davies in his non-fiction book Doctor Who: The
Writer's Tale, the character was developed from the beginning with the
intention of appearing for a whole of the 2007 series, and to later
make guest appearances in subsequent series and crossover appearances
in the show's two spin-offs; Martha subsequently made guest
appearances in Torchwood series two and in Doctor Who series four in
2008 and special episode "The End of Time" in 2010. Martha was also
intended to make guest appearances in the 2009 series of Torchwood and
The Sarah Jane Adventures, but could not due to the actress's other
work commitments.Within the series' narrative, Martha begins as a
medical student who becomes The Doctor's time travelling companion
after an incident at the hospital where she works. After well over a
year (from the perspective of The Doctor and herself) travelling with
The Doctor, Martha parts from The Doctor's company as she recognises
how unhealthy their relationship has become. After returning to life
on Earth, becoming engaged and finishing her medical degree, Martha
finds a newfound level of independence when she is recruited into the
paranormal military organisations UNIT, and briefly Torchwood. Having
faced the end of the world single-handedly during her time with The
Doctor, Martha is recognised for her skills both in the field and in
medicine.Freema Agyeman's first appearance in Doctor Who was in the
second series (2006) episode, "Army of Ghosts", where she played
Adeola Oshodi, Martha's cousin. Martha Jones Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
