I'm sorry to report that the libertarian historian Kenneth Gregg died Friday of congestive heart failure. Gregg was especially interested in recovering the precursors to modern libertarianism, and he found antistatist currents in places ranging from the cooperative movement to the Georgists; he also explored topics ranging from radical puppetry to the life of the early civil rights activist Timothy Thomas Fortune.
Gregg faced some personal tragedies late in his life — two of his children were killed by separate reckless drivers — and his health suffered. I never met Gregg, but we corresponded from time to time, and his emails were always as interesting as his more formal writings; he seemed a decent and intelligent man. Rest in peace.
