Richard Francis Ruggles (1916–2001) was an American economist[1] known for "developing accounting tools for measuring national income and improving price indexes used in formulating government policy."[2]

During World War II he used photographs of destroyed German tank serial numbers to estimate production rates at different factories, solving the German tank problem.[3][4] In 1942 he was awarded a PhD from Harvard University for thesis titled Price Structure and Distribution over the Cycle.[5]
