This information is somewhat correct. Corrugated board is a three dimensional product while cardboard is of two coordinates. The invention of corrugated has generally been attributed to Robert Gair however two men, Thompson and Norris founded a competing corrugated box firm in that same period and probably would contest that position if still alive. Robert gair did invent the folding carton,e.g.,a cereal box,not the corrugated box,as a result of a mishap with a cutting rule. —The preceding unsigned comment was added by 69.120.1.4 (talkcontribs) 12:32, December 6, 2005 (UTC)
