1. Introduction

In this paper, the contributions of the University of Madrid and the Institute of Electricity and Automatics (IEA) in the field of computers and related subjects will be discussed for a period beginning in 1950 and continuing through the mid-1960s.

The Institute of Electricity and Automatics of the Consejo Superior de Investigaciones Cientificas (CSIC -- Higher Council of Scientific Research) was always located on the premises of the Faculty of Sciences at the University of Madrid, which motivated close ties between the two centers and made it possible for most work to be carried out in close collaboration among the researchers of both centers. The references include work from each area of accomplishment, as discussed in the following sections.

2. Analog Systems

The first papers about analog systems dealt with derivation and integration circuits (Santesmases and Manas 1949; 1952).

In 1952, a small group of IEA researchers began the study and design of an electronic differential analyzer. This computer was completed in 1954 and was presented in 1955 to the

first International Analog Computation Symposium held in Brussels (Santesmases 1955; 1956a; 1956b). The multiplier and function generator were described in detail in Santesmases and Ci it (1958) and Santesmases and Ibeas (1958). A two-variable-function generator was designed and built (Ibeas and Aleixandre 1958; 1961). Some refere...
