Major Clifford Hugh Douglas, MIMechE, MIEE, was a British engineer, economist and pioneer of the social credit economic reform movement.

Social credit is a distributive philosophy of political economy developed by C. H. Douglas. Douglas attributed economic downturns to discrepancies between the cost of goods and the compensation of the workers who made them. To combat what he saw as a chronic deficiency of purchasing power in the economy, Douglas prescribed government intervention in the form of the issuance of debt-free money directly to consumers or producers in order to combat such discrepancy.
