Likely named after Calvin Fletcher Jr. (1826-1903), one of the few actual Hoosiers in the “Indiana Colony” that would become Pasadena. Born into a prominent Indianapolis family, Fletcher made his money in agriculture and railroads. In 1869, he built a huge mansion in Spencer, IN which stood as a local landmark for over a century. In 1873-1874, as a founding member of the San Gabriel Orange Grove Association, Fletcher came out west and laid out the townsite of the future Pasadena; in the process, he named Orange Grove Boulevard – and probably Colorado, California, and Columbia boulevards as well. Fletcher owned 180 acres here but barely made use of them: soon after laying out the town, he toured Europe for several years, then went back to Indiana. Fletcher Ave. was named in 1905.
