Original GP Logo
The Gillespie & Powers (GP) logo originated in the early 1960s, following the successful design and construction of two major aluminum melting furnaces outside of the company’s regional area. As the company aimed to expand its operations nationally, the need for a fresh, promotional image became apparent. To enhance the company’s literature, a distinctive logo was required.
At that time, the company was led by two key executives: Charles Albert Gillespie, the founding partner, and John R. Gillespie, the Chief Operating Officer. They sought the expertise of their mutual relative, Jack Sparkman, a principal artistic associate at Monsanto Company, headquartered in St. Louis, Missouri – United States.

Present Day GP Logo
After visiting the company’s offices and engaging in discussions, Sparkman was inspired by two elements: the engineering triangles used in the design process and the survey instruments employed on job sites. The survey instruments utilized a plumb bob, which hung precisely from the center, ensuring accurate positioning on reference points. Sparkman creatively merged these elements into the GP logo.
The triangle symbolizing engineering at the base and the plumb bob representing construction at the top. The two elements converge at a central point, with the GP initials prominently displayed. Despite this thoughtfully crafted design, many at Gillespie & Powers, particularly those in the field, continue to refer to the company as GPX.
