Graham O'Brien is a fictional character created by Chris Chibnall and
portrayed by Bradley Walsh in the long-running British science fiction
television series Doctor Who. In the show's eleventh series, starting
with the first episode, Graham served as a companion of the Thirteenth
Doctor, an incarnation of the alien time traveller known as the Doctor
(portrayed by Jodie Whittaker). His character is portrayed as an
everyman; a retired bus driver in remission from cancer. Graham
returns for the show's twelfth series in 2020.Graham was born in
Essex, during either the late 1950s or early 1960s, saying he was
"only a toddler" in 1962. As a child, Graham attended Sunday School in
Chingford, and sometimes spent summer holidays at Margate and
Whistable. After his mother passed away, Graham's father "got rid of
all her things super quick", unable to keep hold of them, telling
Graham that "she's gone now and that's the end of it".Graham worked as
a bus driver, once having a supervisor who he would recall as behaving
similarly to Thomas Edison. After he retired, Graham still kept in
contact with his friends who also worked as bus drivers.Graham
developed cancer and met his wife Grace, a chemo nurse, while
undergoing treatment. When he told Grace that he was a bus driver, she
remarked that he ought not to be like James Blake, who she called
"Blake the Snake." He learned of her appreciation of Rosa Parks and
that she owned a t-shirt that said "The Spirit of Rosa". Once the
cancer was found to be in remission, Graham married her and had become
her second husband by 2015. Graham O'Brien Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
