 In the former group were ENIAC co-inventors J. Presper Eckert and John Mauchly, who the previous March had departed the Moore School amidst a patent rights dispute to found the first computer company, the Electronic Control Company (later renamed to Eckert–Mauchly Computer Corporation), and took many on the Moore School staff with them; in the latter group were Herman Goldstine (the Army's liaison to the Moore School who served as administrative overseer of the ENIAC's construction) and Arthur Burks (a Moore School professor on the ENIAC design team), lured to the Institute for Advanced Study by von Neumann.Despite the somewhat acrimonious fracturing of the ENIAC/EDVAC group, these figures gave the majority of the Moore School Lectures, with Eckert and Mauchly receiving the highest salaries ($1,200 each), while Goldstine and the others received only travel expenses and an honorarium ($50 per lecture).Lectures were given 5 days a week on weekdays and were from 1 to 3 hours long with afternoons typically reserved for informal seminars.
