Norman Joseph Woodland, who co-invented the bar code along with his classmate Bernard Silver and patented it in 1952, has died last Sunday. He was 91. Bar code’s invention was far ahead of its time. It had to wait until 1974 to make commercial debut in America. Today the ubiquitous bar code is like the oxygen of logistics. The world remains indebted to the beautiful mind of Norman Woodland for helping to keep the tab on goods and articles on the move.
