Samuel Tinga Khendekha Seisay (22 August 1928 – 4 February 2015) was a Sierra Leonean diplomat and pro-democracy activist.
While he was a student, Seisay had a life-changing meeting with Martin Luther King Jr. in Stockholm, which deepened his interest in nonviolent activism.
Seisay proved to be most efficient in this post, especially considering the difficult political climate, and skillfully helped manage the transition.
Seisay was initially tapped to serve as Sierra Leone's Ambassador to Egypt but was instead appointed Consul General to the United States.
Based in the United States, he continued to work internationally and remained devoted to the cause of re-establishing democracy in Sierra Leone.
He has lectured at several universities, including Dartmouth, and published a number of articles and op-eds most notably in West Africa and Christian Science Monitor.
