The chemist that fought in late 19th and early 20th century for pure food and laws to protect consumers against adulterated foods. Dr Wiley worked for the Ag Dept and what was the early USDA. He was responsible for the 1906 Pure Food Law.
Foods in the early 20th century were nasty, just gross.
There is so much in this book. Well written. Interesting, kept me wanting to read.
4⭐️ recommend if you are interested in food history.
