Jacobus, Donald Lines
Donald Lines Jacobus (1887-1970) founded the New Haven Genealogical Magazine in 1922. Ten years later it became The American Genealogist (often referred to as TAG) which he edited until 1960. It was his goal "to raise genealogy to the same high standards as other scholarly disciplines." What became known as the "Jacobus School" centered around him and TAG, which is still published today
In 1930 Jacobus wrote the classic Genealogy as Pastime and Profession which is still considered as a "must have" work by those who are seriously interested in a scholarly approach to genealogy. Between 1930 and 1932 he compiled the three-volume History and Genealogy of the Families of Old Fairfield for the Fairfield, Connecticut, Daughters of the American Revolution.
Jacobus was one of the earliest Fellows of the The American Society of Genealogists, an Honor Society of fifty members chosen on the basis of the significance of their contributions to genealogy.
