Early propellors were Mahogany or Walnut. Hartzell, the US propellor makers, were also a walnut lumber company. Spruce was also frequently used, but virtually all woods have been used and are still in use. Around 1915 the wood of choice became Oak and sometimes Oak over a Spruce core. Oak is stronger than Walnut and Mahogany.

The best wooden props were solid oak. They made them from the core of an oak tree

If "did they use" is the key phrase then according to the source below WWI props were made of pine.
