He was a psychological profiler for the CIA, examining the minds of world leaders such as Saddam Hussein and Kim Jong-il.
But in his later years turned his attention closer to home, penning a book on the mindset of US President Donald Trump.
Jerrold Post, a former political psychologist and author, died from complications related to coronavirus in late November at the age of 86.
Those who knew him have paid tribute to his work.
Magnus Ranstorp, a special advisor to the EU Radicalisation Awareness Network, described Post as "very gentle, kind and with a sharp mind".
His friend psychologist Kenneth Dekleva said Post was a "giant in the field of leadership analysis and a CIA trailblazer".
Jessica Case, a publisher with Pegasus Book who worked with him on his last book on President Trump, told the BBC: "His knowledge and insight into psychology were unmatched. He was endlessly curious."
