Although the invention of the computer was credited to CharlesBabbage, a mechanical engineer and mathematician fromEngland, some believe that the recognition should go to hiscolleague, Ada Lovelace. Born in 1815, Lovelace worked onBabbage's proposed mechanical general-purpose computer, theAnalytical Engine. She is believed by some to have been the firstto publish the first algorithm intended to be carried out by themachine, and thus the first to recognize the full potential ofcomputers. Ada Lovelace blazed a trail for other women inscience. Indeed, Ada Lovelace Day is celebrated in Octoberannually to pay homage to the achievements of women in STEMsubjects: science, technology, engineering and mathematics.Some schools also run "Ada Lovelace" programs, targeted atyoung female students to spark their interest in STEM subjects.In October, achievements of women in engineering arecelebrated.TrueFalseCannot Say
