Another early source, from the time-and-motion studies pioneers:
Process Charts, Frank B. Gilbreth, Lillian M. Gilbreth (1921), American
Society of Mechanical Engineers.
It's available at https://archive.org/details/processcharts00gilb .
Among its symbols are "moved by boy" and "moved by messenger boy".
