Writing is a codified system of standard symbols: the repetition of agreed-upon simple shapes to represent ideas. Recognizable systems of writing developed in 3 major cultures within 1200 years of each other. Sumerian cuneiform developed around 3000 BC, Egyptian hieroglyphs around 2800 BC, and the precursor to Kanji Chinese around 1800 BC. The development of writing allowed cultures to record events, history, laws; theories in math, science, medicine; create literature and more.
By the mid-1700’s, there were special schools established to teach handwriting techniques, or penmanship. Master penmen were employed to copy official documents such as land deeds, birth and marriage certificates, military commissions, and other legal documents. Timothy Matlack was commissioned to write the final copy of the Declaration of Independence, and Jacob Shallus penned the final copy of the Constitution of the United States of America.
