Joseph Hackmey who made his business career in insurance and real estate, having started his career as a physicist and later as an actuary, was first exposed to postage stamps by watching his father devoting time to a collection of King George the Sixth at a very early age. By the age of twelve he became very familiar with the Stanley Gibbons red book of 1949.
The first collection formed was of Israeli issues, taking advantage of the large amount of mail received by the family’s insurance company. Next, collections of British Palestine, Holy Land,Transjordan, and the postal history of the Ottoman Empire were formed. Later on, collections of France, Persia, Romania, Baden, Switzerland, Chile, USA, Mexico, Iraq, Saudi Arabia, Spain, Papal States, and Turkey, were formed plus some BritishCommonwealth areas such as New Zealand, Ceylon, Barbados, Grenada, Canada, Cape of Good Hope, and the six Australian States. Many of the exhibits received Large Gold medals or Grand Prix prizes at FIP internationals.
Joseph is a Fellow of the Royal Philatelic Society London which awarded him a Lee medal, a member of the French Academie de Philatelie, and a member of the collectors club New York. At all of these organizations he presented displays and papers. In 1999 Hackmey was invited to sign the Roll of Distinguished Philatelists at Salisbury.
