The Frisky is marking Black History Month by highlighting the work and achievements of notable African-American women. Each Monday of this month, we’ll feature women whom we would have covered had we been their contemporaries and had the internet existed when they were making their marks. You might have heard of, or even studied, some of these African-American women before, but many aren’t very well known. This week we’re spotlighting notable inventors. Test your knowledge and learn a little trivia by clicking through the slideshow.
