 Mauchly was also suspected and forced to leave the company, and it took him two years to get back to work. In the meantime, the company was in financial difficulty and it was eventually sold to [Remington Rand](https://en.wikipedia.org/wiki/Remington_Rand) in early 1950.

 In fact, the idea for the von Neumann architecture was initiated by Mockley and Eckert, but their credits were removed from von Neumann's paper, [First Draft of a Report on the EDVAC](https://en.wikipedia.org/wiki/First_Draft_of_a_Report_on_the_EDVAC), dated June 30, 1945. Their business was not successful, also due to political reasons.

 Early programmers used punched cards to write code. Punch cards were originally used for data storage from the late 19th century, and were used by the US Census Bureau for census purposes. It is easy to understand if you think of the current [OMR](https://www.google.com/url?q=https://en.wikipedia.org/wiki/Optical_mark_recognition\&sa=D\&source=editors\&ust=1711341049448063\&usg=AOvVaw06E8KEgdfN-gcEH_ZHA4k6) sheet to mark answers.
