Question: Irving Fisher (February 27, 1867 - April 29, 1947) was an American economist, statistician, inventor, and Progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman. Fisher made important contributions to utility theory and general equilibrium.

James Tobin argued that the intellectual breakthroughs that marked the neoclassical revolution in economics occurred in Europe around 1870. The next two decades witnessed lively debates, which led to the new theory being more or less incorporated into the classical tradition that preceded it. In the 1890s, according to Joseph A. Schumpeter there emerged A large expanse of common ground and ... a feeling of repose, both of which created, in the superficial observer, an impression of finality - the finality of a Greek temple that spreads its perfect lines against a cloudless sky. Of course, Tobin argues, the temple was by no means complete. Its building and decoration continue to this day, even while its faithful throngs worship within. American economists were not present at the creation. To a considerable extent they built their own edifice independently, designing some new architecture in the process. They participated actively in the international controversies and syntheses of the period 1870-1914. At least two Americans were prominent builders of the "temple," John Bates Clark and Irving Fisher. They and others brought neoclassical theory into American journals, classrooms, and textbooks, and its analytical tools into the kits of researchers and practitioners. Eventually, for better or worse, their paradigm would dominate economic science in this country. In reviewing the history of utility theory, economist George Stigler wrote that Fisher's doctoral thesis had been "brilliant" and stressed that it contained "the first careful examination of the measurability of the utility function and its relevance to demand theory." While his published work exhibited an unusual degree of mathematical sophistication for an economist of his day, Fisher always sought to bring his analysis to life and to present his theories as lucidly as possible. For instance, to complement the arguments in his doctoral thesis, he built an elaborate hydraulic machine with pumps and levers, allowing him to demonstrate visually how the equilibrium prices in the market adjusted in response to changes in supply or demand.

Using a quote from the above article, answer the following question: When did he come up with utility theory?

Answer: James Tobin argued that the intellectual breakthroughs that marked the neoclassical revolution in economics occurred in Europe around 1870.

Some context: Drescher was born in Kew Gardens Hills, New York, the daughter of Sylvia, a bridal consultant, and Morty Drescher, a naval systems analyst. Her family is from Southeast and Central Europe. Her maternal great-grandmother Yetta was born in Focsani, Romania, and emigrated to the United States, while her father's family came from Poland. She has an older sister, Nadine.
In January 1985, two armed robbers broke into Drescher and Jacobson's Los Angeles apartment. While one ransacked their home, Drescher and a female friend were raped by the other at gunpoint. Jacobson was also physically attacked, tied up, and forced to witness the entire ordeal. It took Drescher many years to recover, and it took her even longer to tell her story to the press. She was paraphrased as saying in an interview with Larry King that although it was a traumatic experience, she found ways to turn it into something positive. In her book Cancer Schmancer, the actress writes: "My whole life has been about changing negatives into positives." Her rapist, who was on parole at the time of the crime, was returned to prison and given two life sentences. After separating in 1996, Drescher and Jacobson divorced in 1999. They had no children. Drescher stated, "I would have been able to conceive but not hold on." Drescher has worked to support LGBT rights issues after her former husband came out. Drescher has stated that the primary reason for the divorce was her need to change directions in life. Drescher and Jacobson remain friends and business partners. She has stated that "we choose to be in each other's lives in any capacity. Our love is unique, rare, and unconditional; unless he's being annoying." On September 7, 2014, Drescher and scientist and conservative politician Shiva Ayyadurai participated in a ceremony at Drescher's beach house. Both tweeted that they had married, and the event was widely reported as such. Ayyadurai later said it was not "a formal wedding or marriage", but a celebration of their "friendship in a spiritual ceremony with close friends and her family." The couple parted ways two years later.
Did she have any children?
A:
They had no children. Drescher stated, "I would have been able to conceive but not hold on."
