The Baldwins represented in this collection were civil engineers from Woburn, Massachusetts.  Loammi Baldwin was born in 1745 and educated at Woburn.  He supplemented his studies by attending lectures at Harvard.  He and his fellow student, Benjamin Thompson (later known as Count Rumford), made instruments to illustrate the principles they had heard about in class.  When the Revolutionary War began, Baldwin was employed in land surveying and civil engineering.  He served as a colonel in the American army and after the war became the sheriff of Middlesex County.  He also represented Woburn in the state assembly in 1788 and 1789 and from 1800 to 1804.  In 1785, Baldwin received an honorary M.A. from Harvard.  From 1794 to 1804, he was the engineer who oversaw the construction of the Middlesex Canal.


Baldwin was married twice.  He and his first wife, Mary Fowle, had four sons and a daughter.  The younger two sons, Loammi, Jr., born in 1780, and James Fowle, born in 1782, followed their father's career path and became civil engineers.  Baldwin and his second wife, Margaret Fowle, had two children, Clarissa and George Rumford.  Under his father's training, George became a draftsman and civil engineer.


Loammi, Jr., along with his brothers, attended Westford Academy.  He continued his education at Harvard and graduated in 1800.  Although he focused on mechanical subjects in school, he studied law in Groton upon graduation.  In 1804, he opened a law office in Cambridge.  Three years later, he closed it, having judged his profession distasteful.  After deciding to become a civil engineer, he went to England to examine public works.  Upon his return, Baldwin pursued construction for the rest of his life.  His efforts were concentrated on works of internal improvements, including roads, canals, and docks.  Among his great works were the dry docks built at the Charlestown (Massachusetts) Navy Yard and the Norfolk (Virginia) Navy Yard, both built between 1827 and 1834 from the same plans.  Baldwin was also engaged in building the Bunker Hill Monument, two buildings at Harvard, and finding a way to introduce pure water to the city of Boston.  At one point in his life, Baldwin was named Engineer of Improvements for the city of Boston.


Although James Fowle Baldwin started his professional life in the mercantile business, he joined his brother, Loammi, in the construction of the Charlestown dry dock.  In 1828, he and his brother were appointed to a commission to make a survey for a railroad from Boston to Albany.  From 1830 to 1835, James worked on the construction of the Boston and Lowell Railroad.  In 1837, he was appointed as a commissioner to examine and report on the Boston water supply.  He served as water commissioner for a number of years.


George Rumford Baldwin, a particularly fine draftsman, divided his time between Woburn and Quebec, Canada.  He designed and built the Boston Marine railway and was consulting engineer for the Charlestown and Quebec waterworks.





The material in this collection reflects the professional activities of the Baldwins.  The elder Loammi Baldwin's work on the Middlesex Canal is recorded in a volume of the history of the canal compiled from Baldwin's papers by his son, James Fowle.  It contains a list of canal acts, subscribers, and building contracts along with a discussion of the progress of building from an early land survey to letters that consider the construction of canal boats.  Letters from William Weston, also an engineer on the project, were copied into the volume.  Notices of payment due dates and meeting times and places document Loammi Baldwin's involvement with the Charles River Bridge.


Three of the manuscripts contain business accounts related to the construction of the Charlestown Naval Dry Docks between 1827-1834.  The waste book (day book), ledger, and "accounts approved" volume all document building materials purchased, prices, and suppliers.  Because Baldwin was superintendent of the entire project, other commodities that supported the project are also listed: office supplies, food and drink, hand tools, payroll, etc.   Another manuscript deals with Loammi Baldwin, Jr.'s effort to upgrade Boston's water supply.  Compiled by Eben A. Lester, it deals with wells in the city.  Lester organized his work by street and then listed the name of the owner of the property, the number of wells on each lot, and the quality of the water.  It offers information on Boston's pattern of settlement and commercial development.


In a manuscript entitled "The Duke of Bridgewater's Coal Mines at Worseley, 1807," and a series of copies of letters in "stylographic manifold writers," Baldwin recounts his experiences on a trip to England.  While at Worseley, he journeyed by canal boat into mines, learned how the coal was mined, then brought to the surface, and finally transported to nearby Manchester.  In letters, Loammi wrote about such topics as gas lighting, the London Bridge Water Works, and fire fighting in London, as well as leisure activities.


Two notebook sketchbooks kept by George Rumford record his travels throughout the 1820s and 1830s.  The earlier volume includes a few illustrated essays (e.g. "Theory of Canal Cutting" and "Architecture"), but it is mainly a long series of identified sketches, mostly in pen, with a few in watercolor, of works and details of civil engineering as well as such objects as weathervanes, wheelbarrows, windmills, and fence posts.  Several railways, a rotary pump, the original aqueduct over the Medford River, details of the Schuylkill Canal, and the Essex Bridge at Newburyport are among the places and projects depicted.  The second volume is almost entirely filled with sketches in pen, pencil, ink wash, and 40 finished watercolors.  The sketches include railroads, dams, canals, locks, waterworks, bridges, buildings, monuments, etc.  The identified locations include Savannah, Richmond, Baltimore, Philadelphia, Washington, Boston, various places in New England, upstate and western New York, Montreal, Ottawa, and other places in Canada.  These sketchbooks lend insight into the training and professional life of a civil engineer.


Other volumes in the collection include an inventory of the estate of James Fowle Baldwin, consisting of his financial resources; a record of soundings at various places in Boston harbor in 1867 and 1868 by Benjamin D. Frost, an assistant to George Rumford; a pamphlet describing the gift of the Baldwin Library of Engineering Works to the Woburn Public Library (the material was subsequently transferred to Harvard); and a volume labeled "Cross Section Book."  It opens with soundings and borings taken in 1867 and includes a number of diagrams depicting water systems and water flow and distribution.  There are also some letters from George T. Moffat.

Consists of a list of Baldwin’s financial resources.  He held stock and notes in utility and railroad companies.  The market value of his investments is included.



92x97.7           Soundings in the Boston Harbor across Fort Point Channel, 1867 and 1868, by Benj. D. Frost.  100 p.


Frost was an assistant to George Rumford Baldwin.  Soundings were taken to determine the depth of the water and were valuable to engineers contemplating harbor improvements.



92x92.8           A statistical account of the wells in the city of Boston taken by Eben A. Lester, July 1834, for Col. Loammi Baldwin.  80pp.


The work is organized by street, followed by the name of the owner of the property, the number of wells on each lot, and the quality of the water (soft, hard, drinkable or not, suitable for washing and other conditions).  Miscellaneous remarks were also included.



92x92.9           Waste book.  1827-1834.  222 p.


Account book detailing the expenses of the building of the Charlestown Naval dry docks of which Loammi Baldwin was engineer.  (He was paid $4000 per annum  plus expenses.)  The volume contains details of supplies and construction on a daily basis.



92x92.10         Ledger book.  1827-1834.  158 p.


Companion volume to the waste book, dealing with the Charlestown dry dock.  It breaks down transactions by the name of the firm or individual that had been contracted.  Both volumes chronicle the purchase of building materials, including white oak timber, pine plank, bricks, slate, and cast iron.  Other commodities that supported the project are also listed: office supplies, food and drink, hand tools, etc.



92x92.11         Letters, Loammi Baldwin, Jr.


A red morocco folder with the spine title “Letters” containing blank books that were called “stylographic manifold writers,” seemingly an early form of carbon paper.  Two of the blank books are filled with copies of letters written from Loammi to family and friends while he was in England.  He often wrote of subjects that held his professional interest, such as gas lighting, the London Bridge Water Works, and fire fighting in London, as well as his leisure activities: a visit to Westminster Abbey, a report on debates in Parliament, and a dinner he attended as the guest of the Humane Society.



92x92.12         Pamphlet from the Woburn Public Library.  1899.


Describes the gift of the Baldwin Library of Engineering Works.  The collection was started by Loammi Baldwin and continued by his sons.  (The books were subsequently transferred to Harvard.)



92x92.13         Cross section book.


The volume opens with sounding and borings taken in 1867.  It also includes a number of diagrams depicting water systems and water flow and distribution from 1904.  A note indicates that some of the soundings were copied from Frost’s field notes (presumably those in .7, above), but no other connection to the other papers in this collection is evident.



92x92.14         Letters, 1875 


Consists of stylographic writers, one of which contains letters from George to Emma describing his travels.  A letter to H. B. Williams regarding problems with an easement reveals this George to be George T. Moffat.  Also included is a lithograph of the Connecticut River Railroad Bridge at Williamsett.  George Duggan was the architect and William Endicott & Co. was the lithographer.
