Close your eyes and picture a computer. Odds are, visions of sleek laptops, RGB-lit desktop towers, and smartphones with edge-to-edge displays just danced through your head. But computed technology did not begin with these marvels of modern microelectronics. Long before vacuum tubes and integrated circuits, an unsung community of mathematicians, engineers, and inventors crafted the first computing devices through intricate arrangements of gears, levers, and pinwheels.
Among these pioneers of mechanical computation, few are as important yet overlooked as Anton Braun – the creative 18th century instrument maker who engineered some of the world‘s first true calculating machines.

Brilliant from an early age yet tragically afflicted with chronic poor health, Braun crammed several lifetimes of innovation into his short 41 years on this earth. His visionary calculating devices presaged machines that would one day enable space travel, financial markets, and incredible scientific advancements. This is the too-often-overlooked story of Anton Braun – the generational genius who helped launch modern computing.
Upbringing in a Family of Tinkerers
On April 22, 1686, in the pastoral hamlet of Möhringen an der Donau, Anton Braun came screaming into the world. The bustling river town sat nesteld amidst the verdant hillsides of southern Germany, where Anton‘s father Hans plied his trade as a master watch and instrument maker.
Surrounded by the ticking gears and constant clinking of his father‘s workshop, Anton absorbed the mechanical inclinations of his family from his earliest days. His own younger brother Johann would likewise grow into a skilled instrument maker, though with none of Anton‘s fiery creative brilliance. By age 14, Anton had already gained a reputation as Möhringen‘s resident mechanical prodigy.

This virtuosity soon attracted the attention of the local aristocracy. Anton‘s intricate sundials and drafting implements found patrons in minor German nobles and merchant princes. But the ambitious young man set his eyes on grander scientific pursuits. In 1708, at the age of 22, he relocated to Vienna, Austria to pursue mathematics and instrument making at the prestigious University of Vienna.
A Brilliant Scientific Career Launched through Patronage
University exposed Anton to rarefied ideas in physics and precision mechanics. But it was under the patronage of Holy Roman Emperor Karl VI that Braun‘s career truly took flight. Appointed Kammeropticus et Mathematicus (Imperial Optician and Mathematician) in 1724, Braun earned the monarch‘s favor through a stunning demonstration of mechanical computation power.
The device that so captured the Emperor‘s imagination was Braun‘s first pinwheel calculating machine. Though built on pioneering 17th century designs by mathematicians like Blaise Pascal and Gottfried Leibniz, Braun‘s device represented a massive leap forward in capability and convenience. Not only could it add, subtract, multiply and divide, but it packaged these functions elegantly into a circular desktop configuration reminiscent of the ornamental table clocks so in vogue among Baroque nobility.
Karl VI found the gilded contraption so marvelous, in fact, that he purchased it outright to adorn his own coveted collection of scientific instruments at the Imperial Museum in Vienna. The Emperor simultaneously elevated Braun to the rank of Kaiserlich Hofinstrumentmacher (Imperial Instrument Maker) – one of the highest honors available to a German scientist at the time.
In a final gesture of admiration, Emperor Karl VI bequeathed Braun an extravagant gift: a diamond-encrusted gold chain worth 500 guilders, himself featured prominently as a medallion centerpiece. Sadly, eight years of war and economic depression prevented Karl VI from ever granting Braun the even more monumental cash prize of 10,000 guilders he had originally promised. Nevertheless, the royal endorsement cemented Braun as a maker of kings and nobles across Europe. Orders for custom navigation tools, sundials, and optical devices poured in from France, England, Spain and the German principalities.
Braun‘s second calculating machine, completed in 1736 after his death by son Anton Jr. and collaborator Phillippe Vayringe, reflected a more compact and portable design.
Now a wealthy man, Braun relocated from Vienna to Prague, then Milan to establish new mechanics workshops nearer his highest-paying clients. He spent these years perfecting clever innovations like a surveyor‘s wheel that automatically measured distances traversed and a "waywiser" odometer for more precise mapping of roads and canals.
Between 1719-1722, Braun collaborated extensively on cadastral surveys with Imperial Engineer Johann Jakob Marinoni, lending his mathematical skills to produce beautifully precise maps of towns and cities across Lombardy. Ever the polymath, he also published acclaimed pamphlets in this period on fortification techniques and navigation using the stars.
Cutting Short a Bright Life with Revolutionary Inventions
Returning to Vienna in 1723, Braun shifted his focus toward his most ambitious goal yet: crafting a calculating machine surpassing even his first crowning achievement. Though smaller in stature, his second calculating device integrated several revolutionary innovations.
Chief among these was a cylindrical component dubbed the central adapting segment. By offloading some of the mechanical complexity into this single specialized part, Braun simplified the broader machine while retaining four-function mathematical capabilities. The cylindrical segment configuration proved very influential, reappearing in seminal 19th and 20th century calculating machines produced by firms like Thomas, Payen, Tate, and Hiller.
Sadly, Braun‘s declining health prevented him from completing this second, compact calculating machine before his premature death in 1728 at age 41. His son Anton Jr. took up the mantle, enlisting acclaimed French instrument maker Phillipe Vayringe to help realize his late father‘s vision. The pair completed the device in 1736 as a tribute to the pioneering mechanicus.
Dubbed the Leupold-Braun-Vayringe Machine for its succession of innovators, this second calculator finally gave the world a convenient, portable computing device for scientific and financial use. Its longevity serves as testament to Anton Braun‘s generational genius – examples remain on proud display at institutions like the Deutsches Museum in Munich, Germany even almost 300 years later.
Lasting Memorials to an Overlooked Pioneer
Though largely forgotten by modern audiences, Anton Braun‘s advancements irrevocably furthered the mechanization of mathematics. Later luminaries like Charles Babbage, William Stanley Jevons, and Dorr E. Felt built upon Braun‘s mechanical foundations to inch closer toward modern electronic computing.
When one gazes upon an Arithmometer, Curta calculator, or any of the other pinwheel computing curios that proliferated in centuries hence, one gazes upon machines only made possible by Anton Braun‘s visionary work. The lavish personal gift from an Emperor now itself resides behind museum glass for all the world to admire.
Not a bad legacy indeed for the tinkerer prodigy from the river village of Möhringen an der Donau! When next you pick up the smartphone that serves as a window into human knowledge, take a moment to remember pioneers like Anton Braun who built the first tentative gears of modern computing‘s incredible machine.
