For instance, Mauchly met with United States Census Bureau official William Madow to discuss the computing equipment they desired.

However, new university policies that would have forced Eckert and Mauchly to sign over intellectual property rights for their inventions led to their resignation, which caused a lengthy delay in the EDVAC design efforts.

After seeking to join IBM and John von Neumann's team at the Institute for Advanced Study in Princeton, New Jersey, they decided to start their own company, the Electronic Controls Corporation, in an office at 1215 Walnut St. in Philadelphia, Pennsylvania.

Eckert hired a staff that included a number of the engineers from the Moore School, and the company launched an ambitious program to design and manufacture large-scale computing machines.

[4][6] The core group of programmers were also hired from the Moore School: Kathleen McNulty, Betty Holberton, Grace Hopper, and Jean Bartik.

These contracts were eventually canceled after the company was accused of having hired engineers with "Communistic leanings" during the McCarthy era.

Straus felt that EMCC's work, besides being promising in general terms, might have some application in the race track business, and invested $500,000 in the company.

It was generally believed at EMCC that Northrop allowed BINAC to sit, disassembled, in their parking lot for a long time before any effort toward assembly was made.

[4] As had happened with BINAC, EMCC's estimates of delivery dates and costs proved to be optimistic, and the company was soon in financial difficulty again.

Mauchly resigned from Remington Rand in 1952; his 10-year contract with them ran until 1960, and prohibited him from working on other computer projects during that time.
