Channel Craft. 12" Wooden Ruler made in U.S.A. from American-grown basswood. New product available November 1, 2019! This ruler celebrates the contribution of African-American women to the history and culture of the United States. We could easily have filled a yardstick! We’ve decided to pay particular attention to women who were involved with the Abolitionist Movement of the early to mid-19th century and the Civil Rights Movement of the 1950’s and ‘60’s. Civil rights heroes Dorothy Height (1912-2010) and Rosa Parks (1913-2005) are represented. The dates listed are birth and death years, when known. We also list one detail about each of the people on the list, either an important accomplishment or the area in which they excelled. The “head” image is that of Harriet Tubman (1820-1913), who escaped slavery and subsequently made some 13 missions to rescue approximately 70 enslaved people, using the network of antislavery activists and safe houses known as the Underground Railroad.
