Eugene Field, Sr. (September 2, 1850 – November 4, 1895) was an American writer, best known for his children's poetry and humorous essays.  Field was born in St. Louis, Missouri where today his boyhood home is open to the public as The Eugene Field House and St. Louis Toy Museum. After the death of his mother in 1856, he was raised by a cousin, Mary Field French, in Amherst, Massachusetts.  Field's father, attorney Roswell Martin Field, was famous for his representation of Dred Scott, the slave who sued for his freedom. Field filed the complaint in the Dred Scott v. Sandford case on behalf of Scott in the federal court in St. Louis, Missouri, from whence it progressed to the U.S. Supreme Court.

Field attended Williams College in Williamstown, Massachusetts. His father died when Eugene turned 19, and he subsequently dropped out of Williams after eight months. He then went to Knox College in Galesburg, Illinois, but dropped out after a year, followed by the University of Missouri in Columbia, Missouri, where his brother Roswell was also attending. He tried acting, studied law with little success, and also wrote for the student newspaper. He then set off for a trip through Europe but returned to the United States six months later, penniless. Field then set to work as a journalist for the St. Joseph Gazette in Saint Joseph, Missouri, in 1875. That same year he married Julia Comstock, with whom he had eight children. For the rest of his life he arranged for all the money he earned to be sent to his wife, saying that he had no head for money himself.

Field soon rose to become city editor of the Gazette.  He became known for his light, humorous articles written in a gossipy style, some of which were reprinted by other newspapers around the country. It was during this time that he wrote the famous poem "Lovers Lane" about a street in St. Joseph, Missouri.

From 1876 through 1880, Field lived in St. Louis, first as an editorial writer for the Morning Journal and subsequently for the Times-Journal. After a brief stint as managing editor of the Kansas City Times, he worked for two years as editor of the Denver Tribune.  In 1883, Field moved to Chicago where he wrote a humorous newspaper column called Sharps and Flats for the Chicago Daily News morning edition. In it, Field made quips about issues and personalities of the day, especially in the arts and literature. A pet subject was the intellectual greatness of Chicago, especially compared to Boston.

Field first started publishing poetry in 1879, when his poem "Christmas Treasures" appeared in A Little Book of Western Verse.  Over a dozen volumes of poetry followed and he became well known for his light-hearted poems for children, perhaps the most famous of which is "Wynken, Blynken, and Nod." Field also published a number of short stories, including "The Holy Cross" and "Daniel and the Devil." Field died in Chicago of a heart attack at the age of 45.
