The Institute of Brewing and Distilling has put online original Horace Brown Lecture given in 1916 titled “Reminiscences of Fifty Years’ Experience of the Application of Scientific Method to Brewing Practice”.
I found it fascinating, but then I'm a beer nerd.
I posted about the most recent winner of the Horace Brown memorial medal here. In his lecture Graham Stewart talked about the wide range of brewing science that Horace Brown's research had covered but reading the 1916 lecture shows how remarkable the advances his research made were. Even in areas where we now know things that Brown didn't we can see that his rigorous scientific method was leading him in the right direction.
