After the Civil War in the United States ended in 1865, James Sloan Hutchinson founded SPCA - the fourth humane society in the country and the first one west of the Mississippi. This all can be depicted in a timeline, showcasing all the major stages of San Francisco’s animal rights group. Two years later, M. H. de Young and Charles launched SF Chronicle. In 1884, before human ambulances appeared in the San Francisco area, the SF SPCA designed and constructed a horse ambulance -- the very first of its kind in the west. In the very first month of its operation, it came to the aid of six disabled horses. As the timeline diagram suggests, SP SPCA built an “Animal Home” at 16th and Alabama Streets, and so on.
