- Association and Role within Society or Entity: Chief Legal Counsel for the California Fruit Growers Exchange (Sunkist); counsel for the American Cotton Exchange; and mastermind behind the Canadian Wheat Pools.
- Contributions to the Cooperative Sector: Sapiro formulated the revolutionary "commodity marketing" cooperative strategy, widely known as the "California Plan." He argued that agricultural cooperatives should move past simple local operations and scale up aggressively to control a high percentage of a single commodity within a region, allowing farmers to collectively stabilize prices, manage surpluses, and break up the monopolies held by railway companies and corporate processors.
- He drafted the Uniform Cooperative Marketing Act, which was adopted by 26 US states and directly shaped the language of the federal Capper–Volstead Act of 1922. This historic federal law established the legal right of agricultural producers to market their goods collectively without violating antitrust laws, effectively safeguarding modern corporate-scale farming cooperatives from prosecution. His organizing trips to western Canada resulted in the formation of the giant Alberta and Saskatchewan Wheat Pools, transforming the North American grain trade.
- Awards and Recognitions: Celebrated by agricultural marketing boards and legal associations across North America; historically cataloged within the Library of Congress archives as one of the most important legal architects of industrial-scale agricultural cooperation in the 20th century.
