Sir Christopher was widely recognised for turning around the fortunes of the telecoms giant BT in the early noughties after penning a 10-point plan.
He then moved to lead the RSC where he oversaw a major redevelopment of the main theatre - as well as managing to cram in performances of all of Shakespeare's works in a year.
A man of many talents, he also fenced for Ireland at the 1960 Olympic Games and after retiring penned his first novel - Ashes In The Wind - in his 70s to great acclaim.
He also wrote a play which was produced in London, Easter Rising And Thereafter.
Sir Christopher was knighted in 1993 for his work as chairman of the Hammersmith and Queen Charlotte's hospitals.
