• “Women have been involved in computing since its inception, and though the proportion of women in the field (about 13%) is far less than are to be found in our society,they still have a strong impact on our industry. The column could easily be filled with just the names of the women who have contributed to the field of computing, but most of them are still unknown, overshadowed by the myriad male innovators and often by their husbands.” (Virginia Tech project on history of computing.)
