Longest Career - UK Entertainer

I was watching the telly over Christmas and heard the joke: Question - how does Brucie keep looking so young? Answer - He doesn't. I know Brucie has been around for a few years, and I thought I'd see if I could find out who has the longest career as an entertainer in the UK.

General caveats - I'm excluding musicians and writers to begin with, and focusing on TV and Radio. I'm also trying to exclude "one offs" at the tail end of careers.

Who	Start	Programme	Finish	Programme	Years
Bruce Forsyth	1939	Come and be Televised	2011	Strictly Come Dancing	72
David Attenborough	1954	Zoo Quest	2011	Frozen Planet	57
Rolf Harris	1953	Jigsaw	2010	Jamie's Dream School	57
Patrick Moore	1957	The Sky at Night	2012	The Sky at Night	55
Nicholas Parsons	1957	The Arthur Haynes Show	2012	Just a Minute	55
Ronnie Corbett	1957	Sheep's Clothing	2011	Ronnie Corbetts Comedy Britain	54
William Roache	1960	Coronation Street	2012	Coronation Street	52
David Dimbleby	1962	Top of the form	2012	Question Time	50

My conclusion would seem to be that Bruce Forsyth does have the longest entertainment career, unless anyone else knows better - happy to take suggestions, or indeed for anyone else with a 50+ year career. Data sources - Wikipedia, BBC, IMDB, Radio Times, BFI Screenonline web sites.

Note - Bruce Forsyth was not on TV between 1939 and 1958, when he hosted Sunday Night at the London Palladium. giving him 53 years on TV, which might make me prefer to put Rolf Harris or David Attenborough at the top of the table.

Edit - 21st Jan 12 - David Frost started 1962 TWTWTW.

Worlds Oldest Zoo

I recently went to Bristol Zoo which claims to be the fifth oldest zoo in the world. Which ones are older, I wonder?


Bristol zoo is currently celebrating its 175th anniversary, originally opening in 1836 - on Monday 11th July. http://www.bristolzoo.org.uk/.


A search on the worlds oldest zoo appears to be easy - London comes up, opening 27th April 1828, but not open to the public until 1847. http://www.zsl.org/zsl-london-zoo/ 


However, Tiergarten Schönbrunn (Vienna Zoo) also claims to be the same, opening in 1752, http://www.zoovienna.at/en/zoo-and-visitors/welcome-worlds-oldest-zoo/


Equally, the Ménagerie du Jardin des Plantes in Paris claims to be the oldest, opening in 1635, with a menagerie added in 1793. http://www.mnhn.fr/museum/foffice/transverse/transverse/accueil.xsp?cl=en  


So, that gives three Zoos that are older and claim to be the oldest, which leaves one other to  come between? It would seem to be Dublin, which opened  1 September 1831 http://www.dublinzoo.ie/


So, that answers the question? Maybe not, as it would seem there are less well know zoos that could fit: Madrid zoo - open since 1770 http://www.zoomadrid.com/, and the more elusive Kazan Zoo in Russia, opened in 1806. http://www.kzn.ru/eng/page3736.htm


I'm not the first person to ask this question, and here are a few other takes: 
http://int.rgo.ru/news/oldest-zoos-in-the-world/
http://www.zoochat.com/2/oldest-zoo-19898/


Of course, its possible to find references to older zoo's that are now closed, but I'll leave this list to zoos that are currently open. My take on the list, from the info I've found is:


Vienna - 1752
Madrid - 1770
Paris - 1793
Kazan - 1806
London - 1828
Dublin - 1831
Bristol - 1836


My conclusion is that Bristol is probably not the 5th oldest zoo in the world. I was going to claim that it is the oldest zoo outside of a capital city, until I found Kazan zoo....


Of course, I must acknowledge Wikipedia for much of my information (principally the first link, but I didn't find that initially):
