# Timeline of women in computing

This is a timeline of women in computing. It covers the time when women worked as "human computers" and then as programmers of physical computers. Eventually, women programmers went on to write software, develop Internet technologies and other types of programming. Women have also been involved in computer science, various related types of engineering and computer hardware.

## 18th century
### 1757

* Nicole-Reine Etable de la Brière Lepaute worked on a team of human computers to determine the next visit of Halley's Comet. The methods they developed have been used by successive human computing teams.

## 19th century
### 1842

* Ada Lovelace was an analyst of Charles Babbage's analytical engine and is considered by many the "first computer programmer".

### 1849

* Maria Mitchell is hired by the U.S. Nautical Almanac Office to work as a computer on tables for the planet Venus.

### 1875

* Anna Winlock joined the Harvard computers, a group of women engaged in the production of astronomical data at Harvard.

### 1893

* Henrietta Swan Leavitt joined the Harvard "computers". She was instrumental in discovery of the cepheid variable stars, which are evidence for the expansion of the universe.

## 20th century
### 1916

* Beatrice Cave-Brown-Cave went to work as a human computer for the Ministry of Munitions.

### 1918

### 1920

* Mary Clem leads the computing lab at Iowa State College.

### 1921

* Edith Clarke files a patent for a graphical calculator for problem solving electric power-line transmission problems.

### 1926

Around 1943–1945, these women "computers" used a differential analyzer in the basement of the Moore School of Electrical Engineering to speed up their calculations, though the machine required a mechanic to be totally accurate and the women often rechecked the calculations by hand. Phyllis Fox ran a differential analyzer single-handedly, with differential equations as her program specification.
