Legal troubles and the Remington Rand acquisition
ERA looked to selling similar machines to a number of customers, but at about this time they became embroiled in a lengthy series of political maneuvering in Washington. Drew Pearson's '' Washington Merry-Go-Round'' claimed that the founding of ERA was a conflict of interest for Norris and Engstrom because they had used their war-time government connections to set up a company for their own profit. The resulting legal fight left the company drained, both financially and emotionally. In 1952 they were purchased by Remington Rand, largely as a result of these problems.
Remington Rand already had a computing division however, after they had purchased the
