Entomological Society of London

"The Royal Entomological Society was founded in 1833 as the Entomological Society of London and is the successor to a number of short-lived societies dating back to 1745. ... the privilege of adding the word "Royal" to the title was granted by King George V in 1933, the Centenary of the Society's foundation."- http://www.royensoc.co.uk am 28.9.2012
