Alexander of Platonius

Alexander was a one-time resident of Platonius who later served as a Federation ambassador for over one hundred years.

Although the Platonians were generally human-sized, Alexander was a dwarf who served as a slave to the rest of the Platonians.

In 2268, the USS Enterprise (NCC-1701) arrived at Platonius. Some members of the crew were taken prisoner, but they eventually escaped and took Alexander with them. 

Alexander eventually began serving as a Federation ambassador - a position which he held for over one hundred years prior to visiting S'ti'ach'aas as a representative of the Federation. His size (roughly the same size as a S'ti'ach) as well as his wisdom and sensitivity were pivotal in convincing the S'ti'ach that they could participate in the Federation as equals.
