Help identify the science fiction legends in these thrift-scored pix of the 1956 Worldcon

Cate writes, "I came across a collection of snapshots at a thrift store and recognized the historic nature of the photos, which documented the 14th World Science Fiction Convention.
I purchased the photos from a thrift store in Santa Barbara, California on December 31, 2015. I am looking for help to identify attendees featured in the photos."

The 14th Worldcon, AKA NyCon II or NEWYORCON, included the infamous Balcony Insurgents incident, which gave rise to the fannish shibboleth, "Dave Kyle Says You Can't Sit Here."

The chairman was David A. Kyle.

The Guest of Honor was Arthur C. Clarke.

The toastmaster was Robert Bloch.

The Secretary was Ruth Evelin Kyle
