- Johannes Kepler (/ˈkɛplər/; German: [joˈhanəs ˈkɛplɐ, -nɛs -]; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae, influencing among others Isaac Newton, providing one of the foundations for his theory of universal gravitation. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural and modern science. He has been described as the “father of science fiction” for his novel Somnium.
- Knitting for Victory — World War I (historylink.org)
During World War I Americans of all ages were asked by the United States government to knit wool socks, sweaters, and other garments to warm American soldiers at home and abroad. Most of this knitting was produced by volunteers working under the auspices of the American Red Cross. During the course of the war more than 6,000 Seattle-area knitters as well as knitters from other parts of the state produced hundreds of thousands of knitted items for the war effort. The United States declared war on Germany on April 6, 1917. Germany surrendered and the war was over on November 11, 1918.
