John EmsleyIn chemistry, John Emsley (1938-) is an English chemist noted for his 2001 book Nature’s Building Blocks, in which he gives a short chapter to each of the first 100 elements, listed in alphabetical order, inclusive of a short history of the discovery of each element, and most-importantly a subsection entitled “human element” (see also: human element), wherein he describes the amount of the element in the average person and what it does. [1] Emsley's Nature’s Building Blocks, to note, was an expanded spin-off of his previous 1989 book The Elements, written for scientist, especially chemists, mostly consisting of tables and numerical data.

Human molecular formula
Emsley’s Nature’s Building Blocks and its “human element” section functioned as the main backbone citation, 2005-forward, to the mass-percent based calculation of the human molecular formula by American electrochemical engineer Libb Thims. [2]

Emsley completed his BS in chemistry at Manchester University and PhD in inorganic chemistry, with a dissertation on phosphazenes (phosphorus-nitrogen ring molecules). He went on to teach at King’s College London for 25-years, specializing in non-metallic inorganic chemistry and very strong hydrogen bonding. In 2001, he was associated with the department of chemistry at the University of Cambridge.
