Julien was born in Mobile in November 1941.  His parents were Julius E. and Jean F. Marx.  He was educated in the Mobile County Public School System, graduating from Murphy High School in 1959.  He majored in business at the University of Alabama, receiving his Bachelor of Science degree in August 1963.  After a two-year term in the United States Army Signal Corps as a platoon leader, including service in Vietnam, Julien returned to Mobile and joined his father in the real estate brokerage firm of Julius E. Marx, Inc.

Julien continued the business of that firm until his death in August 2010.  He was both a real estate broker and developer whose talents and creative ability lead him to devote much of his efforts to his specialty of rehabilitating existing commercial properties.  In his own words, Julien delighted in … “taking properties which had become eyesores and converting them into community assets”… Among his re-habitation projects were the Commerce Building, a mid-rise office building in downtown Mobile; the Creighton Towers, a mid rise downtown apartment complex which he renamed the Tower on Ryan Park; Pinebrook Shopping Center, which he converted to a semi “big box” development; Northcross shopping Center in Pensacola; Parkway Shopping Center, on Dauphin Island Parkway, and numerous other properties.  He served as the broker on the sale of lands upon which the Providence Hospital was constructed and lands on which the Infirmary 65 project was erected.

Julien followed the charitable example set for him by his parents.  They chose to remain out of the spotlight while performing their good works in the community.  So, also did Julien.  He particularly enjoyed being a major donor, year after year, to his favorite charities and organizations.  These included, but were not limited to, the Mobile District Council of the Boy Scouts of America, the Mobile Chapter of the ASPCA; Animal Rescue, and the Boys and Girls Clubs. His love of animals and concern over the forgotten strays motivated him to employ someone to feed stray animals in our area on a regular basis.  Julien once expressed his belief that he viewed himself as a caretaker for the properties he had acquired and developed, until they could be passed on to needy charities.
