HMH traces its origins to the well-known nineteenth-century Boston publishing firm Ticknor & Fields, founded by William Ticknor in 1832, and to The Riverside Press, a printing company founded by Henry Oscar Houghton in 1852. Houghton branched out into book publishing in 1864, later acquiring the successor to Ticknor & Fields and several educational publishers, becoming Houghton Mifflin in 1880. The third important branch of our legacy begins in New York City in 1919 when Alfred Harcourt and Donald Brace founded their publishing company with the goal of bringing modern books to the modern world. In 2023 HMH added the assessment powerhouse NWEA, with a focus on bringing integrated solutions to educators to create growth for every student.
William Ticknor and his first partner buy the Old Corner Bookstore in Boston at the corner of Washington and School Streets and open their business as book publishers and sellers. The store becomes a place where writers, readers, and customers mingle and learn.
1845
A distinguished list
Ticknor and his new partner James Fields begin publishing well-known American authors, poets, and essayists like Nathaniel Hawthorne, Ralph Waldo Emerson, Henry David Thoreau, Henry Wadsworth Longfellow, and Harriet Beecher Stowe, upon whom their reputation is built.
1852
Our roots in technology
Henry Oscar Houghton establishes his printing company in an old building alongside the Charles River in Cambridge, Massachusetts, calling it Riverside Press. He quickly gains a reputation for quality printing as the company grows and expands. He branches out into book publishing as Hurd & Houghton in 1864, then buys Crocker & Brewster in 1872, gaining a distinguished list of educational titles.
1880
Houghton and Mifflin partner
Houghton Mifflin is born with the signing of partnership papers by Houghton and George Mifflin. The firm moves into Boston’s Park Street offices, where it stays for 112 years.
1882
Education market begins
The school and college market is growing rapidly. To meet the demand, Houghton Mifflin establishes a department devoted to it. Its first product solely for schools is the Riverside Literature Series, revolutionizing the teaching of literature in American high schools. Novels, poetry, and essays by American authors are presented in an affordable and portable format that was ideal for students and schools.
1887
Beautiful book bindings
Sarah Wyman Whitman is appointed principal book designer, the first woman at any publishing house to head the department. Whitman’s work is innovative in its simplicity, using mostly natural forms and a distinctive lettering style. She is also a stained-glass artist and made the window in the wall by the café on this floor.
1904
Education market booms
In the early years of the 20th century, the education department of Houghton Mifflin establishes itself as a true professional organization with an educational publishing culture. It hires teachers as editors and salespeople, starts a teacher professional development series, and begins to publish its own books with its own authors while no longer relying on the trade department’s back list. Innovations include having a teacher’s manual within the book and introducing a phonics book.
1919
Tools for teachers
Houghton Mifflin launches Emma Bolenius’s Readers, the first series to include teachers’ manuals with diagnostic exercises. Houghton Mifflin sells 450,000 Readers by 1921.
1919
Harcourt, Brace & Co founded
After working for another publisher for 15 years, Alfred Harcourt and Donald Brace leave to start their own firm. Harcourt and Brace embrace the new ideas of the post-WWI world and introduce many British modernist (Virginia Woolf, T. S. Eliot) and Harlem Renaissance (Claude McKay, James Weldon Johnson) authors to the world.
1920
Modern era textbooks
Modern ideas are also pursued in Harcourt’s education books. Helen Gardner’s Art through the Ages is the first art history text to include non-Western art. Anthologies are introduced in the study of literature, and new topics in biology, like human sexual reproduction and anthropology, are included.
1935
Black reconstruction
Black Reconstruction by W. E. B. Du Bois, a groundbreaking historical study, is the first to argue against the perceived view of Reconstruction as a failure and for the need to eliminate racism for democracy to flourish. Du Bois, pictured above (right), follows Harcourt to his new publishing venture and publishes five books with him between 1920 and 1945.
1941
Curious George
Curious George is published in 1941, after its creators Margret and H. A. Rey escape wartime Paris via bicycle and eventually settle in New York City, signing a contract with Houghton Mifflin for four children’s books. Curious George goes on to become a timeless and beloved children’s character, embodying the curiosity and mischievousness of a child.
1941
Women promoted
During World War II, male editors at Houghton Mifflin join the war efforts, and women are finally promoted to editor roles, from which they had previously been excluded. When the war ends, they keep those positions. One remarkable editor is Dorothy de Santillana, who starts in 1940 and goes on to have a major impact. She brings on Margaret Walker and her best-selling novel Jubilee and fights to publish Julia Child.
1954
Environmental movement begins
Biologist Rachel Carson’s book Silent Spring, published by Houghton Mifflin, documents the way pesticides pollute and destroy wildlife. As a direct result of her painstaking research, the US not only bans DDT but also passes the Clean Air Act in 1963, the Clean Water Act in 1972, and the Endangered Species Act in 1973, along with establishing the Environmental Protection Agency in 1970.
1971
Houghton Mifflin reading
Houghton Mifflin had always been a leader in teaching reading and in 1971 introduces a new program with significant innovations in content and style. Popular literature is included after polling librarians to see what children are actually reading. Linguists contribute information on how language is acquired. A variety of illustrations, typefaces, and page layouts draw kids in, and the program is wildly successful.
1977
NWEA founded
Northwest Evaluation Association takes root when a few Portland, Oregon public school educators propose that a group of school districts in the Pacific Northwest collaborate to improve assessments. Under the guidance of founders Allan Olson and George Ingebo, this collaboration leads to a new organization committed to partnering with educators and districts to improve assessment tools and use data to help all kids learn.
1977
Heinemann US established
Heinemann UK, a British publishing company founded in 1890, sets up an office in Exeter, New Hampshire, and quickly realizes the US market requires its own materials. In 1983 it has its first major bestseller, Writing: Teachers & Children at Work by Donald Graves, and establishes itself as a company devoted to helping teachers.
1982
HBJ moves to Orlando
Harcourt Brace Jovanovich enters a period of expansion during the 1960s and 70s, acquiring both publishing and non-publishing companies, including Sea World. In 1984 HBJ moves its headquarters from New York City to Orlando, Florida.
1985
Computer aided instruction starts
There had always been ancillary materials like flash cards, math manipulatives, film strips, board games, and vinyl records sold along with educational programs. In 1985, the department that made those items changes to the software department and begins the process of integrating computers into instruction and assessment.
1986
First computerized tests
When Susan Smoyer, Ron Houser, and Gage Kingsbury join NWEA, they usher in a leap from paper-based to computer adaptive testing. Students in Portland, Oregon are the first to be given NWEA’s test on a computer. Over the next decade, with an increase in technological innovations, these tests evolve into MAP, or Measures of Academic Progress.
2002
Growth research database is launched
By the late 1990s, NWEA had grown to 17 employees, and in 2002, with a growing body of data on student academic progress, the organization is awarded a grant to build a new research database—providing one of the largest nationwide repositories of student test results. It becomes a vital part of the education research community and positions NWEA as a key education research organization.
2006
A pioneer in educational gaming
With Riverdeep come iconic educational gaming brands owned by subsidiary Brøderbund, which is later combined with Houghton Mifflin. The Oregon Trail, Where in the World Is Carmen Sandiego?, and Reader Rabbit were all created in the 1970s and 80s with the rise of the personal computer and have become some of the most well-known and best-selling educational games of all time.
2007

2017
A new vision
Jack Lynch joins HMH as CEO, putting into place a new vision for HMH’s K–12 business focused on using technology in a purposeful way to increase human connection between teachers and students.
