Who came up with all of this? What is the origin? When did it all happen?
John Jacobs began his teaching career in 1965. While teaching and pursuing his graduate degree, he used historical vignettes as class-room enrichment material and as the basis of his research paper titled Man and the Need For Numbers. However, he never published his manuscript.
He then left teaching and over the next 35 years John worked as a construction field laborer, a contracts administrator, a procurement officer and a warehouse materials manager. The passage of 40 years since he first composed his paper has not diminished his interest in the topic.
