The Road Not Taken 6: Fragments of Our Past Mystery Cache

This next part of the Road Not Taken series is a little different than its predecessors. This series has always been about lesser-known heritage places, and this time, the puzzle brings together the historical figures related to 12 different places across Singapore, each named in honour of 12 well-known Singapore pioneers. There is nothing at the published coordinates as usual

To solve the puzzle, identify the pioneers associated with the 12 locations shown in the image below. Their names are the place names as shown, so no further "zooming in" is required. Please use the original spellings of their name (not their nicknames, or hanyu-pinyinized names), for the purposes of the puzzle. Once done, you'll need to take the initials of their full names in order of the images, and enter it into Certitiude without spaces.

Each pioneer will have a 3-word name, so each image should correspond to three letters, for a 36-letter "keyword". For example, for Eu Tong Sen will correspond to ETS. If the next is Lee Kuan Yew (LKY), and the third is Tan Kah Kee (TKK), then the first nine characters in the "keyword" is: ETSLKYTKK.
