Who Invented Plywood?

Sometime ago there was a listing of the most important inventions of the 20th century.  I thought of that while viewing this video on plywood (it's rather arty and for all the warning about table saws, they don't use a guard)--I owe a hat tip to someone, not sure who.

Anyhow, I went to Wikipedia and found the answer(s):

1. the ancient Egyptians
2. Imannuel Nobel, father of the Alfred of dynamite fame.  Although his Wikipedia entry just credits him with inventing the lathe used in plywood manufacture, but that may have been the key innovation needed to make plywood on a mass scale.

The father invents something which is a prerequisite to modern society and the son something to destroy prerequisites to modern society.  And so it goes.
