Biography

Thorvald Frederick Hammer (1893-1987) was a leading industrialist and engineer in the state of Connecticut for over fifty years. He became president of the Malleable Iron Fittings Company (MIF) in 1935 upon the death of the former president, his father, Alfred E. Hammer. His family had been involved in the management of MIF from its inception in 1864. He had started working with the company at the age of fourteen during his summer vacations and became a permanent employee after graduating from Yale University in 1918 and serving in the U.S. Navy during the First World War. He remained in active service with the company until 1969.

As president of the company, he embarked on a program of modernization, which put the production of malleable iron castings on an assembly line basis. At the same time, he installed dust elimination systems and shower bath facilities to protect the health and safety of employees and to improve the environment of the work place.

Mr. Hammer was also an accomplished engineer in his own right. He made a significant contribution to the development of the galvanizing process and was the holder of several original patents. In 1962, Mr. Hammer resigned the presidency and assumed the position of Chairman of the Board when the company was sold to a group of Connecticut businessmen headed by Robert E. Thompson. Thompson became President of the company. In 1969, the company was sold to Waltham Industries and Mr. Hammer retired chairman emeritus. During his retirement, he was an independent engineering consultant.

Thorvald F. Hammer was also a prominent member of several business boards including Southern Connecticut Gas Co., the American Mutual Insurance Co., and the regional board of the Connecticut National Bank. He was a founder of the Branford Historical Society and served as chairman of the Blackstone Memorial Library of Branford, Connecticut, from 1951 to 1986.

He was a lifelong resident of Branford, Connecticut. He was the husband of State Senator Lucy T. Hammer, and they had one daughter, Alexandra Hammer Clark. He died in 1987 at the age of 93.

(Additional biographical information about Mr. Hammer may be found in Series VI, Memorabilia, Biographical and Historical Records.)

Scope and Content

The papers of Thorvald F. Hammer chronicle the life and career of one of Connecticut's most prominent and gifted industrialists of the twentieth century. They also describe in part the day-to-day workings of the Malleable Iron Fittings (MIF) Company, which Mr. Hammer was involved in the management of for over fifty years. In addition, it provides a close-up view of the Connecticut iron industry, which once formed an integral part of the state's economy.

The papers span the period from 1890 to 1987. They contain Thorvald F. Hammer's personal and business correspondence, a variety of company records such as reports and surveys, personnel records, production and reference materials, historical data about the Malleable Iron Fittings Company, and biographical information concerning Mr. Hammer. The papers contain very little about the Hammer family itself except for a small amount of personal correspondence between Mr. Hammer and his family and friends.

The second category is correspondence to and from company or corporate addresses involving mostly business matters such as product and process information, price and service quotes, complaints, work proposals, and consultation recommendations. It is also filed in alphabetical order by correspondent institutional name. The last category is internal company correspondence concerning the day-to-day management of MIF Co. Included in this category is the internal correspondence to and from Mr. Robert Thompson, who was Mr. Hammer's successor as president of the company. This correspondence is arranged in the order in which Mr. Hammer maintained it.

Models
The Thorvald F. Hammer Papers contain several models created by Mr. Hammer as part of his consultant practice. These models are primarily of various facets of the malleable iron casting process. The exact purpose or date of construction of these models is, however, undeterminable because of a lack of information. In all, there are six models, four of which are free standing and two of which are in boxes.
