Abbott received his education at the City of London School and St John's College, Cambridge, excelling in classics, mathematics, and theology.In 1865, at the age of 26, Abbott became headmaster of the City of London School, where he served until 1889. During his tenure, he was known for his progressive educational views and oversaw the education of notable students, including future Prime Minister H. H. Asquith. After retiring, Abbott dedicated himself to literary and theological pursuits, producing works such as Shakespearian Grammar (1870) and a biography of Francis Bacon (1885).

Abbott's theological writings often reflected his open-minded approach, as seen in his anonymously published religious romances like Philochristus (1878) and Onesimus (1882). His most enduring work, Flatland (1884), is a satirical novella that explores dimensions and societal hierarchies, blending mathematical fiction with social commentary. Abbott's contributions to literature and theology continue to be recognized for their depth and insight.
