I think you are talking about Bill Kurban who was a sound recordist for the BBC he worked on Blue Peter and was one of the sound guys on the Everest ascent in 1971 which failed just below the summit.
He was my uncle on my dads (Edward (Ted) Jones B.1928 London- D.1993 Wrington Near Bristol) side and he died in 1977 in Spain, he had a son Kieran.
My name is Graham Jones and I have a brother Colin we think he changed his name in the 60's as he was credited on Blue Peter as Bill Jones, I can remember he got us Blue Peter badges and autographs from the presenters.
Bills mother was Selina Kurban 1896-1988 she died in Brentwood Essex, father was Thomas Ernest Jones of Oswestry Wales 1900-1949 they married in 1924.
There are still relatives in Lebanon, Selim Kurban who I think is Selina brother so my great uncle he was writing our mother maybe 10 years ago, I have tried to make contact as there are connections with the American University of Beruit (AUB) I think Selims son was an electrical engineer (as I am) it seems to run in the family, unfortunately he died young, I believe there is a scholarship at the AUB in his name, but I have hit a dead end as I think they spell it differently there.
Any way hope this helps, feel free to get in touch
