periodic table 1. Recognition The most apparent difference between chemists and chemical engineers to me is recognition. The public at large understand what a chemist does (because they studied chemistry in school), but there is a lack of recognition of what chemical engineering is . Chemical engineering emerged in its own right the late 1800s with  George E Davis  coining the term ‘chemical engineering’. Increasing understanding of the importance of chemical engineering after World War I led to  IChemE  being established in 1922. Add caption
