Friedrich Accum was born in 1789 in Buckeburg, Lower Saxony. He was a pioneer of gas lighting and helped the public be more aware on unclean food and the dishonest selling of it.
He was a big campaigner for the push of food safety. He published 'Treatise on Adulteration of Food and Culinary Poisons' in 1820. The public became more concerned after reading this book because it revealed that food isn't always clean.
