H. L. Mencken: Henry Louis Mencken (September 12, 1880 – January 29, 1956) was an American journalist, satirist, cultural critic and scholar of American English.  Known as the "Sage of Baltimore", he is regarded as one of the most influential American writers and prose stylists of the first half of the twentieth century.  He commented widely on the social scene, literature, music, prominent politicians and contemporary movements.  His satirical reporting on the Scopes trial, which he dubbed the "Monkey Trial", also gained him attention.

August Mencken Sr.: August Mencken Sr. (1854–1899) was the father of writer H. L. Mencken.  August Mencken founded the "Aug.  Mencken & Bro."  cigar factory in 1873 with a starting capital of $44 ($23 of his own money, $21 of his brother's).  A member of Baltimore's German American community, August was recalled by his son as a high-tariff Republican who ran a nonunion factory and viewed the eight-hour day as ""a project of foreign nihilists to undermine and wreck the American Republic"".  H. L. also recalled that his father downed a generous tumbler of rye whiskey before every meal, including breakfast.

Marion Bloom: Marion Bloom (1891–1975) was H. L. Mencken's lover for much of the early twentieth century - eventually becoming close enough that they seriously considered marriage.  They first met February 1914 when Bloom visited the office of "Baltimore Sun".  Mencken and Bloom ended their relationship in the early 1920s, though Bloom continued to admire Mencken.  Their love letters were published in "In Defense of Marion: The Love of Marion Bloom & H.L. Mencken" in 1996 (ISBN  ).

William W. Woollcott: William W. Woollcott (24 March 1876 — 2 February 1949) was an ink-and-paste manufacturer who lived in Baltimore, Maryland.  Known as "Willie" he was the brother of Alexander Woollcott, and was married to Marie Bloede—daughter of Victor G. Bloede—a good friend of H. L. Mencken and a non-performing member of the Saturday Night Club.  He was known for being a "wit and a bon vivant in his own right" but is best remembered for writing the anthem of the Saturday Night Club whose opening line Mencken included in his New Dictionary of Quotations: "I am a one hundred percent American!  I am, God damn, I am!"  The song took on a brief life of its own gaining "wide popularity among the unregenerate" during the 1920s.

Frank Buck (animal collector): Frank Howard Buck (March 17, 1884 – March 25, 1950) was an American hunter, animal collector, and author, as well as a film actor, director, and producer.  Beginning in the 1910s he made many expeditions into Asia for the purpose of hunting and collecting exotic animals, bringing over 100,000 live specimens back to the United States and elsewhere for zoos and circuses and earning a reputation as an adventurer.  He co-authored seven books chronicling or based on his expeditions, beginning with 1930's "Bring 'Em Back Alive" which became a bestseller.  Between 1932 and 1943 he starred in seven adventure films based on his exploits, most of which featured staged "fights to the death" with various wild beasts.  He was also briefly a director of the San Diego Zoo, displayed wild animals at the 1933–34 Century of Progress exhibition and 1939 New York World's Fair, toured with Ringling Bros. and Barnum & Bailey Circus, and co-authored an autobiography, 1941's "All in a Lifetime".  The Frank Buck Zoo in Buck's hometown of Gainesville, Texas is named after him.

The Philosophy of Friedrich Nietzsche: The Philosophy of Friedrich Nietzsche is a book by H. L. Mencken, the first edition in 1907.  The book covers both better and lesser known areas of Friedrich Nietzsche's life and philosophy.  It is notable both for its suggestion of Mencken's still-developing literary talents at the age of 27 and for its impressive detail as the first book on Nietzsche written in English (only seven years after Nietzsche's death) considering the lack of reliable interpretations of Nietzsche in the Western sphere of letters at the time; Mencken prepared for writing this book by reading all of Nietzsche's published philosophy, including several works in the original German.

Treatise on the Gods: Treatise on the Gods (1930) is H. L. Mencken's survey of the history and philosophy of religion, and was intended as an unofficial companion volume to his Treatise on Right and Wrong (1934).  The first and second printings were sold out before publication, and eight more printings followed.  Its first edition received a major 5-column review in the "New York Times", written by one P.W. Wilson; and the Marxist literary critic Granville Hicks called it "the best popular account we have of the origin and nature of religion."  However, the Protestant theologian Reinhold Niebuhr, writing in the "Atlantic Monthly", claimed that "It is only in dealing with moral and social issues that [Mencken] achieves the heights of complete detachment, and in this case the detachment is that of a cynic rather than that of a scientist."  By the end of its first year "Treatise" had sold thirteen thousand copies.  By 1940 its popularity had waned, and although it went temporarily out of print in 1945, Mencken considered it "my best book, and by far."  At the request of its original publisher Alfred A Knopf, Mencken wrote a revised edition (1946), eliminating (among other changes) a controversial quote about Jews:

A Book of Prefaces: A Book of Prefaces is H. L. Mencken's 1917 collection of essays criticizing American culture, authors, and movements.  Mencken described the work as "[My] most important book in its effects upon my professional career."  In fact, the book was considered vitriolic enough that Mencken's close friend Alfred Knopf was concerned about publishing it because of the massive increase in patriotism during World War I in America.

H. L. Mencken House: The H. L. Mencken House was the home of "Baltimore Sun" journalist and author Henry Louis Mencken, who lived here from 1883 until his death in 1956.  The Italianate brick row house at 1524 Hollins Street in Baltimore was designated a National Historic Landmark in 1985.  Mencken wrote of his home: "“I have lived in one house in Baltimore for nearly 45 years.  It has changed in that time, as I have—but somehow it still remains the same... It is as much a part of me as my two hands.  If I had to leave it I’d be as certainly crippled as if I lost a leg.”"
