Background and History

Dewitt was a child prodigy who entered Professor Lambert’s tutelage at age fifteen alongside his senior brother, John Quincy. Though Dewitt competed fiercely with Quincy at first, he abandoned the rivalry after Quincy solved six solutions to an elite competition problem in four hours—four more solutions and six hours faster than Dewitt. The two later became close friends. 1588

He eventually became one of the world’s most influential mathematicians, winning the Fields Medal while young and developing the Dewitt Conjecture. At international summits, his lectures attracted enormous audiences, and his support for the conjecture heavily influenced the direction of mathematical research. 784 794

Dewitt created the Dewitt Dinner as a recurring opportunity for mathematicians under thirty: young scholars who submit complete solutions to his problems earn a private dinner and mathematical guidance. He also founded Dewitt’s Math Class, an online group where promising mathematicians from around the world discuss problems and receive instruction. 785 802

As he aged, Dewitt’s health and mental capacity declined. He developed multiple organ failure and lamented that he had limited time left to prove his conjecture, teach younger mathematicians, and see the next Fields Medal winner. 1064 1103

After registering as a Chenghuang Human Hibernation Volunteer, Dewitt suffered acute liver failure and underwent emergency hibernation. He became the first person to receive human hibernation through Chenghuang technology. 1177 1194 1243

More than half a year later, Dewitt’s brain was restarted through a Dream Control Helmet. He met Tang Jiang and Deng Puhe inside a simulation of Fengze Garden, initially believing that he had amnesia or had died. 1242 1243

Dewitt was later thawed and underwent a successful eight-hour multi-organ transplant using artificial organs. He publicly thanked Song He, Xiang Xiaotong, Chenghuang Neuron, and the medical team after returning to public life. 1563 1574

When his restored body began deteriorating again, Dewitt became an early volunteer for the experimental next-generation Rejuvenation Drug. The treatment visibly reduced his wrinkles and age spots, restored his ability to run, and enabled him and Deng Puhe to resume intensive mathematics teaching. 1833 1835

Appearance

Dewitt is an elderly white man with unruly white hair and a long, wild beard. Before receiving treatment, he was frail, wheelchair-bound, and visibly near death; later procedures restored his mobility and substantially rejuvenated his appearance. 784 804 1833 1835

• Often used an electric wheelchair before receiving mechanical legs. 784 804
• His prolonged wheelchair use caused slight bone deformities that required surgery before leg installation. 804
• Received high-end Neuron Mechanical Legs with realistic artificial skin. 804
• During rejuvenation treatment, his wrinkles decreased and roughly 90% of his age spots faded. 1835
• Is frequently associated with a cigarette during lectures and problem discussions. 784 799

Personality

Dewitt is humorous, outspoken, and fond of teasing friends. He introduced Deng Puhe as a “buy one, get one free” addition to the Dewitt Dinner, complained about terrible roast-duck sauce with theatrical disgust, and publicly accused Deng and Tang Jiang of “kidnapping” him when they forced him to receive mechanical-leg surgery. 12 1835 804

Despite his confidence and formidable reputation, he is candid about aging and intellectual decline. He admits that his younger self possessed at least twice his current mathematical capacity, and he cannot fully understand the deeper grammar of the language he created. 1102

Dewitt is deeply invested in mathematical legacy. He worries about unfinished work, seeks out talented young mathematicians, and strongly advocates for research into the Dewitt Conjecture. His preference for his own field can make him dismissive of competing directions, particularly the Song He Manifold. 1064 802 794

He also has a mischievous streak. Before entering hibernation, he intended to claim that he had verified the Song He Manifold without giving a proof, hoping his supposed final statement would secure posthumous fame. The plan collapsed once dream communication allowed others to question him directly. 1245

Abilities & Skills

Mathematics

Dewitt is a Fields Medal-winning mathematician regarded as one of the foremost living authorities in the field. His work and lectures are difficult enough that even professional mathematicians often struggle to follow them. 784 799

• Developed the Dewitt Conjecture, a proposed tool for advancing major mathematical problems. 784
• Lectures rapidly and at a highly advanced level. Song He gained multiple Mathematics Progress levels from viewing one of Dewitt’s recorded lectures. 799
• Reviews solutions critically; he can distinguish superficial similarity from a genuine breakthrough in his conjecture. 804
• Identified Tang Jiang as the likely author of an anonymous solution hint through mathematical intuition and assessment of the available candidates. 799
• Mentors promising researchers through private dinners, lectures, and his online class group. 785 802

Cryptography and Dewitt Language

Dewitt studied number theory, algebra, probability, and statistics, applying each field to cryptography as a personal pursuit. 1102

• Created numerous cryptographic variations, ranging from simpler substitution systems to more complex rotor-based ciphers. 1101
• Created Dewitt Language, a mathematical language based on cryptographic principles. 1102
• Left encoded messages throughout his notebook, including references to a treasure map and his hidden life’s work. 1102
• Limitation: His cognitive decline prevents him from calculating many of Dewitt Language’s deeper grammars despite having created it. 1102

Dream-World Adaptation

Following hibernation, Dewitt rapidly adapted to communicating and living through Dream Control Helmet simulations. 1243 1244

• Understood the proposed relationship between accelerated dream cognition and time differences with reality. 1244
• Communicated with the outside world through Morse code transmitted by flickering lights. 1244
• Became a prominent virtual-world figure who received visiting mathematicians and traveled Dream Cities by bicycle during his off days. 1561

Equipment / Items

• Electric wheelchair — Dewitt’s primary means of mobility before receiving replacement legs. 784 804
• Neuron Mechanical Legs — Custom prosthetic legs installed after corrective surgery; allowed Dewitt to walk again. 804
• Dewitt’s codebook — A fragile handwritten notebook containing his ciphers, Dewitt Language material, and hidden messages. 1101 1102
• Dream Control Helmet — Used to restart and connect his consciousness during hibernation. 1243
• Old mobile phone — Used to record the “Dewitt Rejuvenation” video account without filters or cosmetic enhancement. 1833 1835

Relationships

• Song He / Tang Jiang — Student and fellow mathematician. Dewitt personally tutored Tang Jiang on the Dewitt Conjecture, invited him into Dewitt’s Math Class, and entrusted him with the codebook; Song He later led Dewitt’s resurrection surgery. 802 1101 1563
• Deng Puhe — Longtime friend, colleague, and frequent dining companion. Deng supported Dewitt through hibernation, mechanical-leg surgery, dream meetings, and rejuvenation treatment. 804 1242 1835
• Professor Lambert — Dewitt’s former teacher, who taught both Dewitt and John Quincy as child prodigies. 1588
• John Quincy — Dewitt’s senior brother, former rival, and eventual close friend. Dewitt regarded Quincy as far more naturally gifted and regretted being unable to preserve his final manuscripts properly. 1588 1590
• Dewitt’s family — His children and other relatives were devastated by his hibernation; Dewitt distributed his property among his children in his will. 1196
• Xiang Xiaotong — Assisted Song He during Dewitt’s resurrection surgery and monitored communication during his dream-state meetings. 1563 1243

Notable Quotes

“In my prime, my brainpower was at least twice as strong as it is now.” 1102

“There are still too many things I want to do. My Dewitt Conjecture hasn't been proven yet, and I want to know who the next young person to win the Fields Medal will be.” 1064

“Before I die, I also want to be a little mischievous.” 1245

Trivia

• Dewitt’s appetite is notorious; Deng Puhe once described him as “a reincarnation of a hungry ghost” after Dewitt overate and required digestive medicine. 796
• He initially resisted receiving mechanical legs because he feared surgery, though he was visibly pleased when he first saw them. 804
• Dewitt’s annual dinner problems may have several valid solutions; one year, he offered four dinner places because his problem had four solutions. 785
• He voluntarily embraced the nickname “Cyber Mathematics Ancestor” after becoming a virtual-world host for visiting mathematicians. 1561
