Quizplus · Accepted Answer

The Harvard College Observatory Computers were a group of women who made important contributions to astronomy. They were hired by the observatory to perform tedious and time-consuming calculations related to astronomical observations and data. They used pen and paper rather than mechanical adding machines or digital computers. Their work helped to greatly advance the field of astronomy and their contributions were largely unrecognized for many years. The Harvard College Observatory Computers were a group of women who made important contributions to astronomy. They manually classified stars and performed complex calculations used in astronomical research, such as determining the distance between stars. They were not digital computers, cash registers, or calculators, but rather highly educated and skilled women who used mechanical tools to aid in their work.
