CPM Inland history
CPM Inland company history timeline
In 1930, William M. Murphy incorporated Central Pre-Mix Concrete Co. in Spokane, Washington and started down an amazing path that helped revolutionize the ever changing construction industry.
Much has been made of a red herring introduced at the trial to discredit Eckert and Mauchly -- the experiments with computational equipment of Doctor John V. Atanasoff, of Iowa, in the late 1930's.
The first truck-mounted concrete mixers in the Northwest were put into operation by CPM in 1935.
The second path begins in 1946 when John W. Mauchly and J. Presper Eckert started the Electronic Control Company (renamed the Eckert-Mauchly Computer Corporation) of Philadelphia.
In 1949, Remington Rand had completed a magnificent Laboratory for Advanced Research on the shore of Long Island Sound.
In the early 1950's the United States Air Force trained him in the emerging fields of computers and management science, fields in which he has spent most of his professional life.
In 1952 Remington Rand acquired another young computer firm, Engineering Research Associates of St Paul, Minnesota.
They estimated 20 man months ($40 to $50 thousand in 1956 dollars) would be needed to complete the detailed theory, develop the computer programs, and apply the method to some test projects.
Thanks to Morgan's prodding, my project report of March 5, 1957, could read “A model of the Du Pont construction scheduling problem has been formulated and a method of solution has been proposed.
These first efforts were completed July 24,1957.
Planning work began in late December, 1957.
In February, 1958, Mai Demurjian took all our data tapes to Lockheed's large UNIVAC 1103A computer at Palo Alto to work out a whole range of construction schedules using the new program developed by Nathan Knoch of Univac Sales.
Hyde, E.R. “Integrated Engineering Control Study of Engineering Department Project Scheduling,” E.I. du Pont de Nemours & Co., Engineering Department, Wilmington Delaware, January, 1959.
With a heavy computer orientation, what could be more natural than to announce our wares at the 1959 Eastern Joint Computer Conference (EJCC) in Boston, December 1–3.
Fondahl, John W. 1961. “A Non-Computer Approach to the Critical-Path Method for the Construction Industry,” Department of Civil Engineering, Stanford University.

One indicator -- upon Chief Engineer Read's retirement, interest so waned at Du Pont's engineering department that it took until 1968 for them to adopt CPM as standard practice.
How, in 1973, in a dispute between RemRand and Honeywell over payment of royalties, a federal court invalidated his and Eckert's computer patents, and raised doubts in the public mind over their priority in inventing the electronic computer.
In 1983, the Midwives Alliance of North America (MANA) created a Credentialing Committee to gather information about the credentialing of midwives.
By 1985, the Credentialing Committee was working in conjunction with the Standards and Practice Committee and the Education Committee to develop proposals for a voluntary Registry for direct-entry midwives.
In 1986, MANA established the Interim Registry Board (IRB) to develop a test that would measure midwifery knowledge based on the MANA Core Competencies.
In 1991, the first test was administered to groups of midwives across the United States.
The first CPM credential was issued in November of 1994.
After 1995, all candidates were required to take the NARM Written Exam regardless of their licensure status.
The first administration of Form D of the Examination, developed by SMT, was in August of 1996.
In September of 1997, CPM joined CRH in North America.
In 1997, NARM contracted with National Measurement and Evaluation (NME). At this point, NARM established its own applications processing department.
