Fred Herzog (September 21, 1930 – September 9, 2019) devoted his artistic life to walking the streets of Vancouver as well as almost 40 countries with his Leica, photographing - mostly with colour slide film - his observations of the street life with all its complexities. Herzog ultimately became celebrated internationally for his pioneering street photography, his understanding of the medium combined with, as he put it, "how you see and how you think" created the right moment to take a picture.
