[14][15][16] While his mother was against war, it was her collection of history books that first sparked Eisenhower's early and lasting interest in military history. He persisted in reading the books in her collection and became a voracious reader on the subject. Other favorite subjects early in his education were arithmetic and spelling.[17]
His parents set aside specific times at breakfast and at dinner for daily family Bible reading. Chores were regularly assigned and rotated among all the children, and misbehavior was met with unequivocal discipline, usually from David.[18] His mother, previously a member (with David) of the River Brethren sect of the Mennonites, joined the International Bible Students Association, later known as Jehovah's Witnesses. The Eisenhower home served as the local meeting hall from 1896 to 1915, though Eisenhower never joined the International Bible Students.[19] His later decision to attend West Point saddened his mother, who felt that warfare was "rather wicked", but she did not overrule his decision.[20] While speaking of himself in 1948, Eisenhower said he was "one of the most deeply religious men I know" though unattached to any "sect or organization". He was baptized in the Presbyterian Church in 1953.
