### Personal Life and Death
James Tobin married Marion Crawford in 1938; they had six children, including Robert Summers (an economist) and Jane Samuelson (a physician). He was known for his humor, often quipping, “Economics is the queen of the social sciences”—a nod to its interdisciplinary reach. He died on March 11, 2002, in Urbana, Illinois, at age 84.

- Robert Solow (Nobel 1987): Extended Tobin’s work on financial markets and macroeconomic policy.
- Joseph Stiglitz (Nobel 2001): Expanded on Tobin’s work on financial markets and macroeconomic policy.

His debates with Milton Friedman, Friedrich Hayek, and Kenneth Arrow defined 20th-century economic thought, while his work on financial markets and macroeconomic policy ensured its relevance. His ideas on financial stability and speculative bubbles have been adopted by central banks and financial authorities worldwide.

His final book, Inside the Economist’s Mind (2007), reflected on the evolution of economic thought. At his death, The Economist wrote: “James Tobin did not just change economics; he was economics for much of the 20th century.” His theories, textbooks, and students continue to shape policy, from central bank decisions to financial regulations, ensuring his legacy endures.
