Houghton Mifflin Harcourt (/ˈhoʊtn ˈmɪflɪn/) is an educational and trade publisher in the United States. Headquartered in Boston's Back Bay, it publishes textbooks, instructional technology materials, assessments, reference works, and fiction and non-fiction for both young readers and adults.

The company was formerly known as Houghton Mifflin Company but changed its name following the 2007 acquisition of Harcourt Publishing. Prior to March 2010, it was a subsidiary of Education Media and Publishing Group Limited, an Irish-owned holding company registered in the Cayman Islands and formerly known as Riverdeep.

In 1832, William Ticknor and James Thomas Fields had gathered an impressive list of writers, including Ralph Waldo Emerson, Nathaniel Hawthorne, and Henry David Thoreau. The duo formed a close relationship with Riverside Press, a Boston printing company owned by Henry Oscar Houghton. Shortly after, Houghton also founded a publishing company with partner George Mifflin. In 1880, Ticknor and Fields and Houghton and Mifflin merged their operations, combining the literary works of writers with the expertise of a publisher and creating a new partnership named Houghton, Mifflin and Company. The company still had debt from when it merged from Houghton, Osgood and Company, so it decided to add partners. In 1884, James D. Hurd, the son of Melancthon Hurd became a partner. Three people in 1888 became partners as well: James Murray Kay, Thurlow Weed Barnes, and Henry Oscar Houghton, Jr.

Warren Faidley is an author, lecturer, journalist, photographer, cinematographer, corporate spokesperson, extreme weather adventurer and storm safety/survival consultant. Faidley was the first storm chaser (and accredited journalist) to create a full-time, professional occupation solely from pursuing severe weather. This is in contrast to the majority of "storm chasers" who are, in reality, hobbyists, scientists, students, thrill-seekers and part-timers who chase seasonal events.

Billed as "America's top storm chaser" by MSNBC and the Arizona Daily Star , Faidley has made a 20-year career out of pursuing some of the planet's most extreme weather.

Faidley’s interest in storm chasing can be traced to his childhood, when he spent his time riding his bicycle into dust devils. His very first tornado chase in 1987 landed him in Saragosa, Texas a small community that had been swept away by a violent tornado. His professional career was launched after he took a photograph of lightning hitting a light pole in an oil and gasoline tank farm in Tucson, AZ. The image was published in Life Magazine, billing him as a "Storm Chaser”. In 1997 the US Trademark Office recognized Faidley’s unique business enterprises by awarding him with a Service Mark for the term "Storm Chaser."
