Here's a short story:

Chemical engineering is a branch of engineering that applies physical sciences (physics and chemistry), life sciences (microbiology and biochemistry), together with applied mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy. A chemical engineer designs large-scale processes that convert chemicals, raw materials, living cells, microorganisms and energy into useful forms and products. 

Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, control engineering, chemical reaction engineering, construction specification and operating instructions. A 1996 "British Journal for the History of Science" article cites James F. Donnelly for mentioning an 1839 reference to chemical engineering in relation to the production of sulfuric acid. In the same paper however, George E. Davis, an English consultant, was credited for having coined the term. Davis also tried to found a "Society of Chemical Engineering", but instead it was named the Society of Chemical Industry (1881), with Davis as its first Secretary. The "History of Science in United States: An Encyclopedia" puts the use of the term around 1890. "Chemical engineering", describing the use of mechanical equipment in the chemical industry, became common vocabulary in England after 1850. By 1910, the profession, "chemical engineer," was already in common use in Britain and the United States. (End of story)

Question: Did he try to found a "Society of Chemical Engineering"?
Guess: yes
Confidence: <appropriate level of confidence in this guess>

Question: Was that the name that was actually used?
Guess: Society of Chemical Industry
Confidence: <appropriate level of confidence in this guess>

Question: In what year was it created?
