Julian Chain
Jesse Charney
Robert Silverberg states in <a href="http://www.isfdb.org/cgi-bin/title.cgi?34076">Alpha 7</a> that Julian Chain was a pseudonym for Julian May Dikty, but per information documented in <a href="https://mobile.twitter.com/HortonRich/status/1534693006271553537">this Twitter thread</a> that is incorrect. Julian May annotated the entry for Julian Chain in a copy of Barry McGhan's Pseudonym book with <i>'is really Jesse Charney'</i>.
