I learned that Bill Gates was born October 28, 1955. He was the co-inventor of Microsoft. He helped benefit the world by helping us look things up on the internet because we probably would be looking in phone books and going off of previous knowledge. Bill Gates have three children. I didn’t know for college he attended Harvard University. I say Bill Gates is an thoughtful person because he and his wife donated 50,000,000 for people with Alzheimer’s. When Bill Gates turned 13, and his parents enrolled him at Seattle’s exclusive preparatory Lakeside School. I never knew that Bill Gates first wanted a of career was in law. This is what I learned about Bill Gates. The next person is Alexander Fleming. He was born March 6, 1881 and died March 11, 1995 in the UK( United Kingdom). Alexander Fleming is known for help curing disease. If it wasn’t for him most people probably wouldn’t have known that they was sick or what cancer or any disease looks like. He attended St. Mary’s Hospital Medical School. He had one child. Before attending St. Mary’s he was at a shipping office school. I didn’t know to check for testing for different diseases Alexander use to use a bowl and if the bowl molded it was bad and if it didn’t it was safe. Alexander Fleming was an biologist. This is what I learned about Alexander Fleming.Last person is Katherine Johnson she is known for being one of the three African American women to first work at NASA. Katherine Johnson  was born August 26, 1918. She was in high school by the age thirteen.She attended West Virginia State University. Katherine Johnson was not an average person she used her brain and faith for all her problems. She didn’t let her race stop her from being great. Her calculations were so great to were with her NASA had many successful rocket ladings. A quote from her is ” You are as good as anyone in this town, but you are not better than any of them.”  Katherine Johnson was the only African American woman to work in the all white portion at NASA. She was the reason most rocket landings were possible. Katherine has three children. Katherine Johnson is a hero in my eyes.If you feeling down and think you can’t succeed in your trial and area just read an article about Katherine Johnson and maybe you will be encouraged. Personally I love Katherine Johnson because she was determined to be successful and not let people bring her down just because she was African American. This is what I have learned about Katherine Johnson.
