The article chronicles the six pioneering female programmers of ENIAC (1945–1946), the world's first functional digital computer. These women—including Betty Holberton and Jean Bartik—hand-coded the machine by plugging cables and flipping switches without keyboards or monitors, yet were erased from history while male engineers received all credit. Their contributions laid groundwork for modern programming; their stories were only rediscovered in 2022 through Kathy Kleiman's research. This is a critical tech-history piece highlighting systemic bias in recognition and the hidden foundations of software engineering.
