||Sir William Vallance Douglas Hodge FRS FRSE (d. 7 July 1975) was a British mathematician, specifically a geometer. His discovery of far-reaching topological relations between algebraic geometry and differential geometry—an area now called Hodge theory and pertaining more generally to Kähler manifolds—has been a major influence on subsequent work in geometry.

||Herman Kahn (d. July 7, 1983) was a founder of the Hudson Institute and one of the preeminent futurists of the latter part of the twentieth century. Herman Kahn (February 15, 1922 – July 7, 1983) was a founder of the Hudson Institute and one of the preeminent futurists of the latter part of the twentieth century. He originally came to prominence as a military strategist and systems theorist while employed at the RAND Corporation. He became known for analyzing the likely consequences of nuclear war and recommending ways to improve survivability, making him one of three historical inspirations for the title character of Stanley Kubrick's classic black comedy film satire Dr. Strangelove.
