## Summary  
Kathleen Antonelli (1921–2006) was an Irish-American computer programmer and mathematician, best known as one of the six original programmers of the ENIAC, the first general-purpose electronic computer. Her pioneering work laid foundational principles for modern software development. She was inducted into the Women in Technology Hall of Fame in 1997.

## Biography  
- **Born**: February 12, 1921, in Creeslough, Ireland  
- **Nationality**: Ireland, United States  
- **Education**:  
  - J. W. Hallahan Catholic Girls High School (1934–1938)  
  - Chestnut Hill College (1938–1942)  
- **Known for**: Programming the ENIAC, pioneering computer science  
- **Employer(s)**:  
  - Moore School of Electrical Engineering (1942–1947)  
  - Aberdeen Proving Ground (1947–1948)  
  - Eckert–Mauchly Computer Corporation (1948–1950)  
- **Field(s)**: Computer science, mathematics  

## Contributions  
Kathleen Antonelli was a key member of the ENIAC Six, the team that programmed the Electronic Numerical Integrator and Computer (ENIAC) during World War II. Her work involved developing methods for solving complex ballistic calculations manually, which were later adapted for ENIAC’s electronic system. After ENIAC, she contributed to the development of early commercial computers at the Eckert–Mauchly Computer Corporation, including the BINAC and UNIVAC I. Her innovations in programming techniques influenced subsequent software engineering practices.  

## FAQs  
### Q: What was Kathleen Antonelli’s role in ENIAC?  
A: She was one of the six original programmers who developed the first software for ENIAC, translating mathematical problems into machine-readable instructions.  

### Q: Where did Kathleen Antonelli study?  
A: She attended Chestnut Hill College (1938–1942) after graduating from J. W. Hallahan Catholic Girls High School (1934–1938).  

### Q: What awards did she receive?  
A: She was inducted into the Women in Technology Hall of Fame in 1997 for her contributions to computing.  

## Why They Matter  
Kathleen Antonelli’s work on ENIAC marked the birth of modern programming, demonstrating that computers could solve real-world problems beyond pure calculation. Her techniques influenced early software development and paved the way for high-level programming languages. Without her contributions, the transition from manual computation to electronic programming might have been delayed, impacting fields like engineering, science, and business.  

## Notable For  
- **ENIAC Programmer**: Among the first to program the world’s first general-purpose computer.  
- **Women in Tech Pioneer**: Recognized in the Women in Technology Hall of Fame (1997).  
- **Early Commercial Computing**: Contributed to BINAC and UNIVAC I at Eckert–Mauchly.  

## Body  
### Early Life and Education  
- Born Kathleen Rita McNulty in Creeslough, Ireland, on February 12, 1921.  
- Immigrated to the U.S. as a child and graduated from Chestnut Hill College in 1942 with a degree in mathematics.
