Gerard Slevin
Gerard Slevin was born in Cork, Ireland. Slevin was assistant to Edward McLysaght, the Chief Herald of Ireland, from 1944 to 1954, at which time he succeeded McLysaght. He held this position for 27 years until he retired in 1981.
During his time as Chief Herald, Slevin inaugurated a genealogy advisory service, to assist in requests for help from people of Irish ancestry.
Slevin was also heavily involved in the design of the European flag, a circle of 12 golden stars on a deep blue background, and in recognition of this was made a member of the Académie Internationale d'Héraldique. His exact role in the design is uncertain. According to some sources he was the actual designer of the flag; others suggest a more peripheral role. The story that the flag's design was solely that of Slevin continues, however.
