Mark L. Stewart

Mark L Stewart is an American writer and editor of magazines, books and web sites. He is best known for his books on sports, history and popular culture. Stewart was born on July 7, 1960 in New York City. He has published over 250 books, written nearly 1,500 athlete profiles in the print and electronic realm, and developed marketing and public relations materials for clients ranging from Denny's and Pizza Hut to Dick's Sporting Goods and Major League Soccer. Stewart is the managing editor of Edge Magazine and Radius Magazine, New Jersey lifestyle magazines with a combined annual circulation of 600,000 copies. Stewart is a principal of JockBio.com, a popular sports information site that posts full-length athlete biographies, and The Big Pitch television show on Fox Business Network.

Stewart’s first publishing job was managing editor of Racquet Magazine (1988–1992), an upscale tennis publication. He continued to edit magazines throughout the 1990s and 2000s, focusing on business publications in the Sports Product, Footwear, Consumer Electronics, Telecommunications and Outdoor Recreation industries. He also pursued numerous freelance assignments during this time, many of which focused on sports and popular culture. His corporate clients included BMG, Zurich Reinsurance, Radio Spirits and the National Basketball Association. He wrote the copy for the NBA’s 1992 sales catalog and created the slogan “I Love This Stuff.”

Stewart published his first book in 1993, The Ultimate Insider’s Guide to Baseball Cards (Crown Books). In 1994, Stewart helped International Masters Publishing create its popular Sports Heroes, Facts & Feats continuity product. He oversaw a team of 38 freelance sportswriters that produced more than 500 gatefold athlete profiles.

Also in 1994, Stewart was hired by Grolier to author the All-Pro Biography book series of authorized biographies. The series was aimed at reluctant readers, and featured athletes recounting the challenges and triumphs of their childhoods. Among the athletes Stewart worked with on the series were Dan Marino, Jerry Rice, Steve Young, Barry Sanders, Isiah Thomas, Chris Mullin, Martin Brodeur, Tony Meola, Jeff Gordon and Florence Griffith-Joyner. With his reputation established as a sports author in the educational publishing field, Stewart continued to produce sports books for Grolier, Franklin Watts, Children’s Press, Millbrook Press and other companies in the field. He also wrote books under the pen names Rachel Rutledge and Caleb MacLean.

In 2002, Stewart entered into a partnership with two publishing professionals with whom he had worked for nearly a decade on a number of projects, Ron Jaffe and Mike Kennedy. They named their company Black Book Partners LLC. In 2003, Black Book Partners launched JockBio.com. Each week the site posts a new, comprehensively researched and professionally written biography of a popular athlete. By 2009 JockBio.com was drawing more than a million readers a year.

In 2004, Stewart worked with All-Pro defensive end Simeon Rice on his autobiography, Rush to Judgment. The no-holds-barred account of life as a football star was well reviewed in various publications, including Sports Illustrated. Also in 2004, Stewart and Kennedy collaborated on Hammering Hank: How the Media Made Henry Aaron. Both books were published by the Lyons Press. Lyons later published Mummy Dearest, a book spawned by the TV series Mummy Road Show. Stewart and Kennedy worked with scientists Jerry Conlogue and Ron Beckett, the stars of the show. In 2008, Stewart and Kennedy partnered with two more scientists, Jeffrey Garside and Amy Tilmont, on a six-book series for NASCAR, published by Lerner Books. They are also co-authors of the award-winning Lerner titles Long Ball, Swish, Goal, Score and Touchdown. These titles explore the history and culture of a sport from the perspective of its “quintessential” or signature moment.

Since 2005, Stewart has authored more than 100 books in the Team Spirit series by Norwood House Press. Each Team Spirit book covers the history and culture of a professional sports team. The series expanded into college football and hockey in 2009. Stewart continues to edit magazines, including EDGE and Radius. Among the public figures he has interviewed in recent years were NBC’s Brian Williams, Dr. Mehmet Oz, artist Peter Max, and New Jersey Governor Chris Christie. Stewart also edits the NJSportsHeroes.com web site, which profiles more than 400 of the Garden State's best athletes.

Mark Stewart lives in Monmouth County, New Jersey overlooking Sandy Hook and the Atlantic Ocean. He is married to Sarah Converse Wilson, whom he met at Duke in 1978. They have two children, Mariah (1992) and Rachel (1995). Stewart serves as board secretary for Monmouth Hills and the Twin Lights. Both are National Historic Landmarks.

Mark Stewart was raised in a publishing family. His grandfather was Lester Markel (1894–1977), Sunday Editor of the New York Times for more than 40 years. Stewart’s first name MARK and middle initial L (which is not an abbreviation) create a phonetic version of “Markel.” Stewart’s parents, Jack (1919–1999) and Helen (1918–1990), were also publishing executives. His father worked at the Times for more than 30 years, and was head of the Book Division before it was sold. Stewart’s mother, who worked professionally as Helen Markel, was the Articles Editor for The Ladies Home Journal and McCall’s during the 1960s and 1970s, and wrote for several other magazines, including Sports Illustrated. His stepmother, Linda Stewart is a syndicated travel writer.

Mark Stewart went through the Ethical Culture School system and graduated from the Fieldston School in the Bronx, NY in 1978. He attended Duke University and graduated with a degree in History in 1984.
