Dr. Ben Carson: Black history is American history – and this is why it's all worth celebrating

That is the beauty of America; we care not about the color of your skin, but the content of your character.

Before leaving the house, you reach down to tie your shoes, ready to walk out the door. In 1883 a young black man by the name of Jan Ernst Matzeliger invented a quicker way to make shoes called "lasting," which attached the top half of the shoe to the sole.   I am a firm believer in the fact that the United States of America is and always has been a nation full of decent people that care for their neighbors and love one another. As you approach the grocery store you may notice refrigerated trucks delivering fresh produce to stock the shelves. In 1938 a Black man by the name of Frederick Jones invented portable refrigerator units to transfer fresh produce, perishable foods and even blood. He would later go on to be the first African American to receive the National Medal of Technology.
