The New York Times obituary of Frank Lautenberg reported, "When he joined the company, he was its fifth employee. But it grew rapidly, and by 1982, when he left the company as its chief executive, it was one of the largest computer service companies in the world, with 15,000 employees." However, a 2011 obituary in the Times of Henry Taub, a founder of ADP, reported, "Senator Lautenberg left the company in 1983 after winning election to the United States Senate."
When did Lautenberg leave ADP? One article reports 1982, and the other article reports 1983. It would seem that one of the two articles should be corrected, because it's logically difficult for them both to be accurate.
