Is legal knowledge valuable? For businesspeople, legal knowledge has been an essential part of their craft for a very long time. The earliest known contract was written on a cuneiform tablet in 2750 BCE, where a farmer drafted into the military of King Sargon I contracted with another farm to grow and secure his crops in his absence in exchange for half of the grown produce. Contracts involving sales and purchases, rentals, labor contracts, co-partnerships and other agreements were used as early as 2000 BCE. Centuries later, the Roman Empire had formally trained legal experts who advised on legacies, guardianships, and contracts. In the modern era, prominent seventeenth-century merchant Gerard de Malynes noted that a businessperson was not a “compleat merchaunt” without knowledge of commercial law. Legal knowledge was so important to Joseph Wharton that, when he established the first collegiate school of business at the University of Pennsylvania in 1881, business law was one of five subjects he specified for the curriculum for what is today one of the most respected business schools in the world.
