Charles R. (Charles Robert) Darling

Charles Robert Darling was a British engineer and science lecturer, born around 1870. Records of his books and catalog listings connect him with works such as Heat for Engineers, Liquid Drops and Globules, and Pyrometry, all centered on the practical understanding of heat, temperature measurement, and the behavior of liquids.

A trade and biographical reference describes him as an engineer and notes that by 1911 he was living in Plumstead, London, and working as a lecturer in science at the City and Guilds of London Institute. That fits well with the character of his writing, which is technical but approachable, aimed at readers who wanted science explained in a useful, real-world way.

His surviving books show a range from specialist instruction to more accessible popular lectures. Pyrometry focuses on measuring very high temperatures for industrial and laboratory use, while Liquid Drops and Globules brings the physics of surface tension and fluid motion to a wider audience. Even where details of his personal life are scarce, his published work leaves a clear impression of a writer devoted to making physical science understandable and useful.
