Augustus De Morgan was born in 1806 and died in 1871. DeMorgan was an English Mathematician and Logician. DeMorgan's Laws are mathematical theorems and laws of logic proven by mathematical statements.

Math theorems: 1) the complement of a union of two sets is equal to the intersection of  the complements of the sets. 2) the complement of the intersection of the the sets is equal to the union of the complements of the sets."

Laws of Logic: 1) the denial of conjunction of a class of propositions is equal to the disjunction of the denials of a proposition. 2) the denial of disjunction of a class of propositions is equivalent to the conjunction of the denials of the propositions.

While his mathematical statements prove his theories variations will occur dependent upon the branch of mathematics being studied. His theorems are mathematical statements used in digital electronics circuits, logic operations and more.

These are rules relating the logical operators "and" and "or" via negation.  You can see an online detailed description of this at wikipedia.com  Hope this helped
