I want to publicly apologize to Chelsea Manning for misgendering her (using her pre-transition name) in my book BIOINSECURITIES on p135. I drafted the chapter before I knew of her gender transition and did not catch the error in edits. Thanks to Matthew Donovan for alerting me to this mistake. I am mailing a separate apology directly to Manning. My error is all the more severe since I criticized media outlets for failing to use feminine pronouns to refer to Manning in a 2013 blog post. My publisher has agreed to correct the mistake when the book is reprinted.
