During his 40-year career with the Times, Cunningham captured the fashionable residents of New York on a daily basis.
"He's never missed a day of work. He worked seven days a week," his assistant John Kurdewan told Business Insider.
In the field, Cunningham wore his blue jacket and camera like a second skin, rode his bike (his preferred mode of transportation) around Midtwon Manhattan, and looked out for city-goers with singular senses of style.
While Cunningham's work was visible to all in his column, few were offered a behind-the-scenes look at his process and his life. But Kurdewan, who has worked alongside Cunningham for the past 10 years, provided a small glimpse into the life of the beloved photographer through his Instagram account, workforbillc.
In remembrance of Cunningham, we share some pictures from Kurdewan's page that look into life of the late photojournalist.
