Explanation

The Harvard Mark I (IBM ASCC) was the first automatic digital computer to successfully perform long sequences of arithmetic and logical operations without human intervention (completed in 1944). 'Analytic' refers to Babbage's never-built Analytical Engine. Mainframe is a category, not a specific machine. UNIVAC-I came later (1951).
