The Alan Turing 90 Computable Pen
The National Museum of Computing and the London Mathematical Society are celebrating the 90th anniversary since Alan Turing published in 1936 his paper "On Computable Numbers". A paper that changed the world.
The conference "Turing's Legacy and the Future of Computing" is taking place at Bletchley Park on 16 -18 September 2026 bringing together some of the world's top mathematicians, philosophers and computer scientists to discuss how Turing's original logic continues to define modern computing. They will discuss the direct line between Turing's 1936 paper and current advancements in AI, logic and hardware innovation. To read more see https://www.tnmoc.org/computable90-conference-details
Conway Stewart in association with the National Museum of Computing has launched the Alan Turing 90 Computable Pen to celebrate this event and there will only be 90 made.
The Pen - Limited Edition of 90
Engraved on the top of the pen is the conference logo with a portrait of Alan Turing and the words "Computable 90".
Made in England and based on the iconic Conway Stewart Churchill pen in Classic Black with Sterling Silver rings, the barrel is engraved with the sequence of prime numbers. The sequence begins with 2,3,5,7,11,13,17.. All numbers that are only divided by one and themselves.
Around the wide sterling silver cap band are engraved the English Hallmarks to prove the purity and the pen's origin. To set this pen apart from any other pen is the special grey rings around the section and the cap top making this very distinguished. The limited edition number is engraved on the end of the barrel.
Each pen comes with a certificate of authenticity and a copy of Alan Turing's paper "On Computable Numbers" published in 1936 in the Proceedings of the London Mathematical Society.
The Paper that changed the World
Alan Turing invented computer science by trying to solve a deep logic puzzle called the "Decision Problem" (Entscheidungsproblem), which asked if a mathematical method could automatically prove any math statement true or false. To tackle this, Turing's groundbreaking 1936 paper defines "computable numbers" to precisely describe what a human clerk following fixed rules could calculate. He conceptualised a hypothetical device now called a "Turing Machine". By defining the exact limits of what numbers can be calculated, Turing built the theoretical blueprint for modern computer science.
Available as a Fountain Pen or a Rollerball.
Each fountain pen is fitted with a large 18ct gold nib available in EF, F, M or B widths.
The National Museum of Computing
This pen is brought to you by the National Museum of Computing based at Bletchley Park, England. An amazing museum which is home to the world’s largest collection of working historic computers; from the Turing-Welchman Bombe and Colossus of the 1940s through the large systems and mainframes of the 1950s, 60s and 70s, to the rise of personal computing, and culminating with mobile computing, the internet, video games, and robotics. A proportion of each pen sold is given to the Museum to help with their running costs. To take a virtual tour of the Museum visit their website https://www.tnmoc.org

The Pen That Signed a £2 Billion Contract
When National Grid came to sign the £2 billion Eastern Green Link 4 contract, they reached for a British made Conway Stewart pen designed for the occasion. Hand made in Emsworth, Hampshire, the barrel design replicates the actual cable sheath used on the Prysmian subsea cable. British infrastructure, signed with a British pen.

A WWII Navigator's Conway Stewart Pen Unearthed
In September 1943, two B‑17 Flying Fortresses collided over the Essex countryside, killing 20 young American airmen. Eighty‑one years later, local historian Sue Lister uncovered a Conway Stewart No. 236 fountain pen from the wreckage—a burgundy‑and‑black marble relic believed to have belonged to navigator 1st Lt Arthur Ross Moore. This pen, a symbol of wartime resilience and British craftsmanship, will soon be displayed at the RAF Hornchurch Heritage Centre, preserving a story of bravery and fleeting wartime bonds.

Queen Camilla Signs Historic Declaration with Conway Stewart
Queen Camilla’s swift signature at Stationers’ Hall on 15 July 2025 links today’s monarchy to a guild that has tended the written word since 1403. The Stationers’ Company, once candle‑lit scribes beside St Paul’s, later policed printing under a Tudor charter and rebuilt after the Great Fire. Now, as the Worshipful Company of Stationers and Newspaper Makers, it trains new talent and preserves its rich archive, while fellow member Conway Stewart still crafts pens by hand—a living thread binding past and present.

Agatha Christie’s Detection Club
In 1930, Agatha Christie, Britain’s queen of crime, picked up her fountain pen to craft puzzles that hooked a nation. Her 66 novels, like The Murder of Roger Ackroyd, spun clever whodunit tales for a Britain craving smart escapes after the Great War. With Dorothy L. Sayers, she started the Detection Club, a secret group of writers using fountain pens to write mysteries that let readers play detective. In a 1930s world of jobless queues and global fears, Christie’s stories offered order, her pen a lifeline for fans seeking answers in a good plot.
