Marc J Fletcher was born in New Jersey on January 25th 1899. He had a typical childhood and worked in his family's tavern in Weehawken, NJ. When the great war began Marc enlisted as many young men did. He served in 1st Division, 16th Infantry regiment. He was stationed in France and served in the Battle of Picardy and the second Battle of the Marne. He received the Distinguished Service Cross.

When the war ended he found a job working for the Peninsular & Oriental Steam Navigation Company. The job required him to travel extensively, so using what free time he had he studied the local cultures and customs of the places he visited. Marc was fascinated with the occult practices he found in places such as India, Egypt, Tibet, China, Mongolia, and many of the Caribbean islands. His work had him experience such things as sailing the Nile one month and climbing through the mountains of Kashmir the next. Seeing and experiencing many things he would write about in later years. Incorporating many of his adventures into the works involving Professor Strange.

He met and became friends with many notable men of the age. Such as the composer Arthur Bliss, who later wrote an orchestra piece about Adam Zero. And the noted southwest painter Ben Konis.

He wrote his first short story for the small press magazine Occult Tales to Astonish in the October 1919 issue. The story featured a young American soldier fighting off hordes of undead Germans in the trenches of World War 1. Many more stories followed over the next few years.

Marc returned to America in 1930 and met his future bride Denise, herself an accomplished artist. The two fell in love and were married in a small ceremony at the Jersey Shore.

His first great success came with the advent of the Pulp Hero. Such as Doc Savage, The Shadow, and The Spider. He was called by his editor Stan Sitarski at Standard Publishing and asked to create a new hero for them to use. Marc had two he had been tinkering with. One was a science fiction character named Adam Zero. The other was a Professor of the Occult named Hannibal Strange.

The editor chose Strange as the character they would use. Marc went to work crafting stories for the new monthly magazine Professor Strange, Master of The Occult. The Magazine was a small hit for the struggling company.

For the January 1934 issue of Professor Strange Magazine they decided to run Adam Zero as a backup feature. The character was an immediate success and was quickly spun off into his own magazine that would run for over twelve years.

A radio show and Saturday Serial soon followed along with Comic Books and toys. Many products carried the Adam Zero label until the late sixties. When the final cartoon was created and run in 1967. Since Standard Magazines was one of the smaller publishers and allowed Marc to retain all copyrights to his characters he was involved with all aspects of his creation.

Marc and Denise traveled extensively as they grew older going on many expeditions into the jungles of Africa and returning to his old haunts in Europe. In 1984 they began a trip into Tibet. Their expedition was lost and no sign of them was ever found.

Many attempts to create movie and cartoon projects fell apart after that time as the family refused to sell the copyright to the characters.
