Smithsonian Institution - United States National Museum - Bulletin 240: Contributions From the Museum of History and Technology

In Short

This volume brings together eleven historical monographs detailing key breakthroughs in Western engineering, applied science, and instrument design. Through precise archival research and technical analysis of surviving artifacts, the text traces how early mechanics, clockmakers, bridge builders, and chemists solved fundamental physical problems. From the trial runs of early internal-combustion carriages and double-hulled steam warships to the microscopic chemistry of organic molecules and the global measurement of gravity, the collection documents how abstract scientific theory was brought into direct contact with physical materials, forging the infrastructure, tools, and institutional collections of the modern industrial world.

The Story

The narrative of this collection unfolds as an incremental progression of human problem-solving, moving from early mechanical experimentation to complex global systems of measurement. It opens in the late nineteenth century with mechanics Charles and Frank Duryea constructing their early self-propelled carriage in Springfield, Massachusetts. Facing the novel challenges of internal-combustion engines, the brothers improvised, housing Samson batteries and ignition coils under elevated wooden seat cushions and testing primitive wooden and metal baffle mufflers during secret night runs along rural roads.

The focus then shifts backward in time and upward into cosmic mechanics with the story of Father Francesco Borghesi and his craftsman partner, Bertolla. Driven by a radical theory of an immovable spherical net suspended by magnetic forces, Borghesi pushed a reluctant Bertolla past the point of despair to construct a astronomical clock. This intricate device mechanicalized true and mean planetary time, true lunar positions, and solar and lunar eclipses, converting daunting astronomical equations into visual index movements.

The book then turns to heavy civil and mechanical engineering, detailing how physical structures were redesigned to withstand newly calculated forces. Wendel Bollman addressed the limits of structural materials by designing iron bridge trusses built around hollow, multi-segment Phoenix columns. These rolled wrought-iron forms solved severe compression problems and replaced less reliable cast-iron structural elements on American railroads. In naval engineering, Robert Fulton developed his massive double-hulled "Steam Battery," a heavily timbered catamaran warship built with five-foot-thick solid wooden sides and an enclosed central paddle wheel to protect its machinery from broadside fire during coastal defense operations.

Parallel to these mechanical advances ran the development of precision tooling, electrical measurement, and chemical synthesis. Machinists developed master-screw methods to standardize thread cutting, while early electricians advanced from the crude physiological shock tests of Cavendish and Volta—who mapped electrical currents by touching electrodes to human eyelids and tongues—to sensitive deflecting electroscopes and magnetic multipliers. In chemistry, investigators unraveled the atomic architecture of living matter, mapping the four basic nitrogenous bases, ribose sugars, and phosphate groups that form nucleic acids, ultimately isolating the energy-carrying molecule adenosine triphosphate (ATP) from mammalian muscle tissue.

The narrative reaches its engineering peak in subaqueous and underground construction, focusing on the Hoosac and St. Clair tunnels. Here, the sheer resistance of rock and unstable earth forced the development of the pneumatic Burleigh rock drill and cast-iron tunneling shields, establishing modern underground transit methods. In railway transport, small light locomotives like the Pioneer demonstrated the early utility of Stephenson shifting-link valve gears. The volume concludes with the history of institutional preservation—such as the acquisition of the historic Freiburg cathedral pharmacy—and the nineteenth-century geodetic enterprise, where scientists swung reversible pendulums across continents to measure minute variations in Earth's gravitational pull and compute the precise geometric shape of the planet.

How It Unfolds

The mechanical carriage takes the road Engineers Charles and Frank Duryea assemble an early internal-combustion vehicle, solving electrical and acoustic problems by improvising battery mounts under seat cushions and fashioning experimental wood-and-metal mufflers. Secret late-night road tests in Massachusetts establish the practical viability of self-propelled American automobiles.

Cosmic geometry in clockwork Father Francesco Borghesi conceives an astronomical clock based on an intricate theory of a fixed celestial sphere and magnetic axis poles. Despite mechanical setbacks and the despair of his clockmaker partner Bertolla, they build a dial mechanism that calculates planetary movements, lunar phases, and visible eclipses.

Forging structural iron and timber warship hulls Wendel Bollman invents a segmented wrought-iron column that resolves compression stresses in railway bridge trusses. Simultaneously, Robert Fulton designs a massive twin-hulled catamaran warship featuring five-foot-thick solid timber walls designed to shield its internal steam paddle wheel from enemy shot.

Refining electrical measurement and chemical architecture Physiologists move past using frog legs and sensory shocks as electrical detectors, creating sensitive gold-leaf electroscopes and coil multipliers. In chemical laboratories, researchers isolate the component parts of nucleic acids and identify adenosine triphosphate as the central energy carrier in biological muscle.

Conquering mountain rock and measuring the geoid The invention of the pneumatic Burleigh drill accelerates the excavation of the Hoosac Tunnel, establishing standard underground mining techniques. Scientists like Charles Sanders Peirce take reversible pendulums into deep tunnels and across oceans, gathering gravimetric data to calculate the exact oblateness of the Earth.

The People

• Frank and Charles Duryea: Practical mechanics who design and construct an early working internal-combustion automobile. Frank handles much of the physical assembly, tinkering with Samson batteries, crude mufflers, and engine timing to achieve successful road trials.
• Father Francesco Borghesi: A secular priest, scholar, and astronomical theorist who conceives a complex model of the universe. Driven by intense devotion to his astronomical theory, he shames and encourages his partner to complete an unprecedented astronomical clock.
• Bertolla: A provincial clockmaker who partners with Borghesi. Repeatedly overwhelmed by the lack of specialized tools and the complexity of the priest's designs, he despairs of his skills but ultimately executes the clock's intricate gearing.
• Wendel Bollman: An inventive iron master and engineer who designs the famous Bollman truss. He solves structural compression weaknesses in early iron bridges by developing the multi-segment Phoenix wrought-iron column.
• Charles Burleigh: A mechanical engineer at the Putnam Machine Works who invents a practical, reliable pneumatic rock drill. His drill replaces slow hand-drilling at the Hoosac Tunnel, reducing costs by half and establishing the prototype for modern mining drills.
• Charles Sanders Peirce: An assistant for the U.S. Coast Survey who travels to European laboratories to obtain advanced Repsold-Bessel reversible pendulums. He conducts extensive gravimetric experiments in tunnels and field stations to determine the Earth's ellipticity.

In Its Own Voice

"This contrivance muffled the sound considerably, but, as might be expected, soon began to smoke."

Don H. Berkebile captures the unvarnished practical friction of early engineering tests while describing Frank Duryea's initial wooden automobile muffler box.

"... electrodes in the nose merely produced a 'more or less painful' pricking feeling, with no impression of smell."

Robert A. Chipman recounts Alessandro Volta's 1800 experiments, illustrating how early scientists used their own sensory organs to detect electrical currents before physical instruments existed.

"The advances made in tunneling have not perceptibly removed the elements of uncertainty but have only provided more positive and effective means of countering their forces."

Robert M. Vogel reflects on civil engineering history, noting that technological progress changes the scale of human tools rather than eliminating natural hazards.

What It's Really About

The collection centers on the transition from empirical, trial-and-error craftsmanship to standardized, mathematically driven applied science. It argues that technological progress is rarely a smooth sequence of isolated genius; rather, it is an accumulative, highly iterative struggle against physical friction, material weakness, and limited diagnostic tools. The text reveals how progress depended on standardization—whether cutting uniform screw threads, rolling identical structural iron shapes, or establishing international reference units for measuring gravity. Underneath its descriptions of gears, valves, and chemical formulas, the book explores how human ingenuity translates abstract mathematical geometry and physical hypotheses into durable mechanisms that alter transport, medicine, structural design, and our understanding of the Earth's physical structure.
