Career at Stanley Gibbons
Stanley Phillips joined Stanley Gibbons in 1906 and rose to become Chairman of the firm.
Returning to the firm after the end of World War I he was asked to create the Stanley Gibbons Monthly Circular  and from 1922 he was the Editor of all Stanley Gibbons publications. In 1926 he became joint Managing Director with William Hamilton Andrews and after Hamilton Andrews retired in 1946 Phillips became sole Managing Director. After his cousin Frank Phillips died in July 1953, Phillips became Chairman of the company.
In 1934 he created the "Simplified" catalogue at Stanley Gibbons which has since become the key work "Stamps of the World".
Phillips has been called a "crusader for philately"  and he was particularly noted for his many books on Stamp Collecting that introduced a whole generation to the hobby. His titles were usually for the beginner and always referred to stamp collecting and not philately.
