I dunno, I’m not sure you can attribute either the industrialization of bread production, or the artisanal bread movement, to any one invention or person.

For example, you could tell exactly the same story about the electric mixer leading to faster bread making, leading to large-scale production of low-quality bread; and Raymond Carvel reviving artisanal French bread with his popularization of autolysis (mixing the flour and water and resting it before adding yeast).
