author
Best known for a witty early-20th-century send-up of business advice and family expectations, this author turned the father-son letter format into sharp, easygoing comedy. His work still feels lively for the way it mixes satire, affection, and generational friction.

by Charles Eustace Merriman
Charles Eustace Merriman is a little-known author now, but his surviving work suggests a lively comic voice. He wrote Letters from a Son to His Self-Made Father, published in 1904, an epistolary novel presented as replies to Letters from a Self-Made Merchant to His Son.
The book follows Harvard student Pierrepont Graham as he writes home to his businessman father in Chicago, using humor to play up the clash between practical ambition and youthful perspective. It was illustrated by Fred Kulz and dedicated to Mark Twain, which fits the book's light, satirical tone.
Reliable biographical details about Merriman himself are scarce in the sources I could confirm. A second book commonly attributed to him is A Self-Made Man's Wife: Her Letters to Her Son, published in 1905, suggesting he was part of the same playful literary conversation around family, success, and American manners.
