Who invented the square target on the basketball backboard ?

Dear jnl1-ga
I was unable to find the answer for your question but the following
may be of interest.

"The next significant development in basketball history occurred in
1893 when both the hoop and backboard were invented. The first hoops
were actually formed out of chicken wire and were developed because
the peach baskets did not have an opening for the ball to fall
through. Backboards were also created at this point in basketball
history in order to keep spectators in the balcony from interfering
with game play. The first backboards in the history of basketball were
also made out of chicken wire, which the players would utilize to
guide the ball into the basket. Wooden backboards became mandatory in
1904, and glass backboards were admissible by 1909."

"1947 - Rectangular target required on backboard"(I was unable to
confirm this date).

history of the game.
