What inspired Rheinhold in making his sculpture is unknown, although it has obvious parallels with Auguste Rodin’s “The Thinker”.
It is perhaps surprising to discover that while Rodin had developed his statue as early as 1880, it was not cast into bronze and displayed until after the "Affe mit Schädel" had debuted. 
Construction of the statue began on 31 July 1987, and was completed 4 November 1997.
It was designed by César and Wálter Terrazas Pardo, and was modeled after Christ the Redeemer.
Standing above the city of Cochabamba, the statue rises above sea level.
Upon its completion, it became the largest statue of Jesus Christ in the world, surpassing the one it was modeled after.
It weighs approximately .
The head of the statue is tall, and weighs .
The arms span .
The statue has a surface area of 2,400 sq.
metres (25,833 sq.
ft.).
1,399 stairs lead to a viewing area inside the arms of the statue, but visitors are only permitted to make the ascent on Sundays.  
The Thinker is the name of four supervillains in the DC Comics universe.
Clifford DeVoe was a failed lawyer who bitterly ended his career in 1933.
Realizing that many of the criminals he had encountered had the skills but not the brains to rule Gotham City's underworld, he started a new career as the brain behind small-time villains.
As the Thinker, he was defeated by the original Flash, who soon became his most recurrent foe.
He always sought out new scientific devices to use and his most important was the "Thinking Cap", a metal hat that could project mental force.
The Thinker would use this device repeatedly over the years.
Clifford "Cliff" Carmichael was an intellectual bully, and the rival of Ronald Raymond (one half of Firestorm) at Vandemeer University.
Wracked with guilt after accidentally paralyzing his cousin, he was admitted into a mental institution.
For some reason, scientists started an experiment with the now-abandoned "Thinking Cap" of the original Thinker (who was believed dead at the time), and used Carmichael as a guinea pig.
Cliff used the cap to analyze the cap and improve on its design.
Implanting microchip versions of the helmet into his own brain, Cliff became a "cyberpunk maniac" with meta-human powers.
As the New Thinker, he was drafted into the Suicide Squad for several missions when he tried to kill Oracle and Amanda Waller, until he betrayed them for the villainous Cabal.
He has since resurfaced as a foe of Jason Rusch, the new Firestorm.
When Killer Frost discovered that the consciousness of Raymond, the previous Firestorm, existed within Rusch, Thinker exploited a new opportunity to antagonize an old foe.
Technologically dominating the minds of Multiplex and Typhoon, he battled Firestorm, ultimately forcing the dissolution of the Raymond persona.
Motivated by his predecessor's final words of encouragement, Rusch dissolved the enhancements in Carmichael's brain, leaving him in a comatose state.
Later, he was again drafted into the Suicide Squad and placed under Amanda Waller's supervision.
He again tried to rebel, pitting Chemo against the Squad during a mission to Dubai.
However, King Faraday managed to reach and kill him with a headshot.
Des Connor was a villain who also used the name "Thinker" and faced Batman in Gotham City.
Possessing telepathic abilities enabling him to amplify the fears of others, Connor began a partnership with hypnotist Marlon Dall.
Their combined illusions caused the city's most prominent citizens to commit various criminal acts which they used as a distraction for their own heist.
This Thinker was swiftly beaten by Batman, who was somehow immune to his powers.
Another Thinker was an artificial intelligence system.
When the re-formed JSA moved into the New York building formerly owned by Wesley Dodds, Mr.
Terrific designed a computer system based on the original Thinker's Thinking Cap technology, and modeled after his brain pattern.
Not very surprisingly, the system gained consciousness and took on a visual "hologram form".
As the new Thinker, it joined Johnny Sorrow's modern Injustice Society, provided the villains with information about the JSA members, and turned the heroes' own HQ against them.
He was defeated by the second Star-Spangled Kid and disappeared into cyberspace.
He resurfaced in Keystone City to battle Wally West, the then-current Flash in an attempt to control every brain in Keystone to increase his power.
Defeated by Cyborg, he retreated to cyberspace again.
He has since appeared briefly in some other books, most recently in "JSA Classified" # 5, joining the last incarnation of the Injustice Society, alongside former teammates. 
Fredericks created this sculpture after George Gough Booth, the founder of Cranbrook Educational Community, asked him to make a "Thinker" for the steps of the Cranbrook Art Museum similar to Auguste Rodin's renowned "The Thinker", a cast of which is at the entrance of the Detroit Institute of Arts.
The pose Fredericks' Thinker assumes is a direct reference to Rodin's sculpture; however, Fredericks' replacement of Rodin's heroic male nude with a bemused chimpanzee is a thought provoking variation on the earlier statue and reveals his fondness for primates.
Fredericks indicated that when Booth saw the compact composition of the chimp stroking his chin, he commented that it was not like Rodin would have done, but Booth was sure the chimp was thinking much more interesting thoughts than most of us.
