Lucia Chamberlain (1882–1978) was an American novelist. Her 1909 book was the basis of the 1916 film The Other Side of the Door, and her 1917 short story "The Underside" formed the basis of the 1920 film Blackmail. The 1916 film The Wedding Guest is also based on her writing.

By the time the 1401 was introduced, electromechanical systems based on punched cards were widely used to manage business operations. These large and unwieldy machines — sorters, collators, punched card calculators and tabulators – each had unique functions and were used together to solve large-scale business problems. For example, inventory manage...
Just about every recent electronic computer has a similar block diagram if you stand far enough back: There are only three major sections: 1. The Central Processing Unit (CPU) is the part that actually computes things… CPUs can add, subtract, sometimes multiply and occasionally divide, plus perform a host of other operations like copying and compar...
Of course any computer’s I/O devices are critical, as that’s where programs and data go in, and answers come out. While many I/O devices were added during the 1401 family’s lifetime, the machine started out with only three: 1. As noted, punched cards were critical to data processing using tabulating machines long before what we’d recognize as progr...
The 1401 doesn’t have a keyboard or display, so how would all that important business data get into the computer in the first place? The 1401 could read the data from punched cards, but where did they come from? For that, there’s another machine in the CHM lab, called a keypunch, where data entry operators could type in the data, one card at a time...
For those of us interested in how computers work, the 1401 fits into a transitional phase in the development of modern computers. Many characteristics are still very familiar, but some are quite different because of the focus on the “unit record”1 one-punched-card-at-a-time paradigm. As shown above, the machine’s internal architecture lines up well...
The 1401 was certainly not the biggest computer on the block when it was introduced, but the focus on modest cost and compatibility with existing business processes made it a very successful machine. Thousands were sold, and by 1965, half of all computers in the world were of the 1401 family, spawning an entire generation of programmers who first l...

Claffey, 1967, Dickenson Publishing1401 ( MCDI ) was a common year starting on Saturday of the Julian calendar, the 1401st year of the Common Era (CE) and Anno Domini (AD) designations, the 401st year of the 2nd millennium, the 1st year of the 15th century, and the 2nd year of the 1400s decade.
The IBM 1401 is a variable-wordlength decimal computer that was announced by IBM on October 5, 1959. The first member of the highly successful IBM 1400 series , it was aimed at replacing unit record equipment for processing data stored on punched cards and at providing peripheral services for larger computers.
