Sir Marcus Setchell was dubbed Sir Marcus a Knight Commander of the Royal Victorian Order (RVO) and received the honour for services to the Royal Family.
Chatting to Prince William, Sir Marcus discussed his 24 years working for the Queen. According to the Mirror, he said: "Well of course it's a great honour and it's very nice that I was able to serve her for 24 years and that the culmination of it was that Prince George should be born.
"Being a gynaecologist and obstetrician must be one of the nicest jobs in the world."I think even after doing this job for 40 years every birth is exciting, moving and lovely."
And talking about delivering baby Prince George back in July, he said: "The job of doing it is just the same pleasurable, lovely experience and one hopes for the couple as well...
"There were slight added tensions because of the interest of your profession (the media), and the world."
On a trip to 1st Battalion Irish Guards, at Mons Barracks in Aldershot, on Monday for St Patrick's Day, Prince William kindly cleared up rumours about Duchess Kate expecting a second baby.
According to the IB Times, Regimental Sergeant Major Ray Collister asked Prince William whether there's a second baby on the way, to which he replied: "Maybe one day. One's enough at the moment."
