David J. Mason, owner and founder of HMG ePublishing, LLC, is an award-winning author and digital publishing entrepreneur, who has been on the Internet since 1997providing technological and telecommunication services. His digital publishing curiosity began during the very early formation stages of the digital publishing industry when he converted one of his previously published traditional manuals into an electronic book. An advocate for digital publishing, he has perfected ebook publishing, production, promotion, distribution, and fulfillment.

Before starting HMG ePublishing, Mr. Mason served in a variety of chemical industry leadership positions, culminating as Vice President for the Hatco Corporation. He handled the Company's environmental affairs and safety programs, regulatory management, corporate imaging, and strategic special assignments such as environmental issues related to potential new acquisitions. Before this position, he served with Velsicol Chemical, ICI Americas, and Hercules Corporation.

A Civil War and Black history enthusiast, Mr. Mason researched Parson, Joseph, and Henry's military service and wrote The Self-Liberation of Parson Sykes based on his findings in September 2022. It is a documentary novel that describes their true self-liberation ordeal and actual events drawn from a variety of sources, including published materials and official military records. In the trilogy, the first novel profiles Parson’s evolution from enslavement and self-liberation by running away from the Williams’ farm. The next book, Enlistment in the XXV Corps, will narrate Parson’s ordeal through the pathway of contraband to a United States Colored Troops (USCT) soldier he took to gain his freedom. The XXV Corps regiments were the first Union forces to enter and capture the fallen Capital of the Confederacy, Richmond, Virginia. In the last book in the trilogy entitled, Emancipated in Southampton County, the story ends with Parson accomplishing his mission and achieving his goal. Parson Sykes will buy property to farm, fight for human rights, and live by the self-determination principles he postulated.

Mr. Mason, the great-grandson of Parson Sykes, was born in Norfolk, Virginia, and grew up there with his parents John Lee Mason and Bertha Sykes Mason. Mr. Mason is the author of the Environmental Compliance Tool Kit (Thompson Publishing Group, 1994) and the Internet Marketing Tool Kit (HMG ePublishing, 2006). He holds a Master of Science degree in chemistry from Hampton University in Virginia, a Bachelor of Science degree in chemistry from Norfolk State University, and is a graduate of the United States Army War College.
