Most Senior Fan

Just as with Most Senior SF Writer, we can ask who is the most senior fan at various times. This could be eldest in age or eldest in years in fandom.

Note that we're using fan in the proper fannish sense of being involved in fandom, and not in the mundane sense of liking sf — there is no hope of knowing who liked sf at any given time. As a practical matter, we're also limited to well known fans as others have left little or no trace of their activities.

N.b., to keep this list from growing without limit, please do not list people who entered fandom after 1950 or who were born after 1935. The idea is to celebrate especially long fannish careers.
