1910-1940

old treating Extend forest resources - Improved use of preservatives to extend the service life of railroad ties and utility poles thus requiring fewer trees.

Low-cost housing - Developed the first low-cost, plywood panel prefabricated house, helping to pioneer the factory-built house.

Use renewable materials - Developed new adhesives and timber connectors, thus allowing the manufacture of laminated wood arches for use in arenas, churches, and other large structures rather than using nonrenewable materials.

Use new species - Determined the fundamental properties of various wood species, thus allowing the substitution of many species for those few that were favored and being overcut.

beam installationReduce defects - Developed the fundamental wood-moisture relationships, which led to the design of the internal-fan dry kiln for drying wood and proper drying schedules. Applying this technology greatly reduced lumber defects, thus reducing waste and conserving timber.

Enhance forest management - Developed the semichemical pulping process that significantly increased the yield of pulp from a given amount of wood, thus extending the wood supply. It also increased the variety of woods that could be used in pulp, thus enhancing forest management.

Chemicals from wood - Enhanced the understanding of the complex chemistry of wood, providing the basis for information on naval stores, chemical intermediates, extractives, explosives, rayon, flavorings, alcohol, fuel and many other chemical derivatives.
