The hidden name is:
First, as noted by @JerryDean in comments, we can see from the Example puzzle that:
If we number each of the cells in the 2x5 grids with digits from 0-9 in order along the rows, the digits in the white highlighted cells can be arranged so as to form the sum of the internal angles of the shape in the corresponding position in the diagram:
Importantly, this teaches us that...
...we should interpret the grids in the first puzzle image as highlighting digits that can be arranged to represent a specific angle, in degrees.
Specifically, like so:
Note next that...
...if you look at the equivalent rows of the second puzzle image, there are angles of these matching sizes!
Now look at the third puzzle image, and...
...overlaying the second image, see which digits these angles trace a path through:
What are these? Well, put them all together and they look like...
Years! Specifically, 1856-1943.
If we combine these with the additional numbers provided by the OP 107 71, and interpret these as a concatenated day and month number, we can form a pair of dates:
10/7/1856 - 7/1/1943
Which 11-letter person was born on 10/7/1856 and died on 7/1/1943? No doubt quite a few(!), but the most famous of these is probably the inventor and engineer, Nikola Tesla, a man of many obsessions!
