In the question Is the location of an aircraft spoiler really that vital? the accepted answer states "Surfaces behind the CoG act as stabilisers, keeping the nose pointing forward. An aeroplane has vertical and horizontal tail surfaces at the back just for this purpose."
I agree that this seems straightforward, to a layman (me). So why then were so many of the first aircraft built 'backwards'. Taking a look at the Wright Flyer
Image (C) Bay Images
as an example. There are many other examples from the earliest days of aviation. Why did many put the elevators up front, thereby destabilizing the whole thing?

I am not sure you are correct that most early planes placed the elevator at the front. For example, Otto Lilienthal's gliders had the tail at the rear.
The Wright brothers were strongly influenced by Lilienthal's work, but were also very anxious to avoid his fate, and believed they would obtain control he lacked by placing the elevator at the front (amongst other things).
It turned out that their Flyer was in fact very unstable, and difficult to control well - but controllable enough.
They also apparently felt that a tail at the rear would be more susceptible to landing damage.

Alphonse Penaud and Lilienthal had the tail in the back, correct. But Santos-Dumont in 1906 and Gabriel Voisin also put the horizontal tail in the front (the Voisin designs had two, one forward and one rear, to be doubly sure they can be stabilized). So in the short period from 1903 to 1907 all aircraft had the tail in front.

The placement of the elevators at the front of aircraft is rather

the pilot in the event of a crash. (The pilot of this aircraft lies
next to the engine on the lower wing.) But there is also a static
performance advantage when the elevator is placed forward. Lifting
wings have a natural tendency to flip tail over nose because of the
way the pressure is distributed.
So they were not necessarily backwards so much as different considerations were taken under advisement during the design.

It's not destabilizing to put the elevator or horizontal "tail" in front, as long as you place the CG sufficiently forward that a large portion of the wing itself is well behind the CG and effectively acting as a tail. The fact that the forward elevator or canard is trimmed to generate positive lift, is what allows you to place the CG well forward in this manner.
$endgroup$
$begingroup$
Now, another related question-- why did the Wrights place vertical "curtains" in front of the CG (forward of the pilot) on some of their aircraft? It never made much sense to me.
