Probably through a connection with Frank Van Vleck, a former professor of engineering at Cornell, who built the cable road in Los Angeles and engineered the cable road in San Diego, Hebbard received employment as a bona fide architect to build the powerhouse for this system.
Active operations did not begin, however, until Frank Van Vleck
arrived in August 1889.
Van Vleck, a graduate of Stevens Institute of Technology was a professor of mechanical engineering at Cornell University.
He was the chief engineer for the Los Angeles Cable Road completed in 1887 and it was his success there that attracted the attention of San Diegans.
See the San Diego Union
, June 8, 1890, pages 1-2, for further details.
Perhaps Hebbard's work in Los Angeles and his
attendance at Cornell
linked these two men to the cable road in San Diego
