Animal Proteins

A technical manual from the early 20th century that maps the chemistry of animal proteins and their industrial uses. Hugh Garner Bennett traces the molecular behavior of proteins found in hides, bones, and connective tissue, explaining how these materials become leather, glue, gelatin, and other essential trade goods. The book documents a pivotal moment when traditional craft knowledge began yielding to scientific method, when a tanner's intuition became explicable through colloid chemistry and protein structure. Bennett systematically breaks down protein composition, classification, and the chemical transformations that turn raw animal matter into durable, useful materials. For historians of chemistry, this offers a genuine glimpse into how early industrial scientists understood and optimized processes that had been practiced for centuries. For anyone in traditional leather working or book conservation, it provides context for techniques that persist today. This is not a narrative book but a period artifact of applied chemistry, revealing the science behind trades that built civilizations.
