  Relational database inventor Edgar Ted Codd dies at 79
Ted is survived by his wife Sharon Codd (the mother of OLAP), four children and six grandchildren.
Sharon Codd is a famous relational theoretician in her own right, and co-authored the 12 rules of OLAP with Ted in 1993.
Codd's most famous quote (in my opinion) was when he was asked why he chose the word "normalization" to describe relational database modeling.

 From the Editor: Edgar (Ted) Codd, 1923-2003   (Site not responding. Last check: 2007-10-26)
By all accounts, Edgar F. Codd, known as Ted, was a brilliant man. Among his accomplishments was the development in the early 1970s of a relational model for data management—a sophisticated and complete theory for storing and manipulating large amounts of business data.
Ted Codd was born in 1923 to a large family in Portland, Dorset, England.
The crux of Codd's solution was that data, rather than being stored in a hierarchical structure, be stored in simple tables composed of rows and columns in which columns of like data would relate tables to one another.

 Smart Computing Encyclopedia Entry - Codd, Edgar Frank “Ted”
Edgar Frank “Ted” Codd is credited with originating the relational approach to database management in 1970 while working as an IBM researcher.
Codd then joined with Chris Date, another relational database expert who worked with Codd at IBM and who expounded on Codd’s theories, to form Codd and Date International in 1984.
Codd received the A.M. Turing Award in 1981, and he was elected to the National Academy of Engineering in 1983.

 E. F. Codd - a Whatis.com definition
E. Codd (Edgar F. "Ted" Codd) formed the concepts for organizing and accessing data that are embodied in the relational database, the predominant approach to data organization in today's business world.
Codd saw the need to reduce or eliminate redundancy in data and to allow data to be accessed through logical rather than physical identification.
Codd also believed that a database management system should provide a standard access approach so that an application program did not have to be aware of how the data was organized.

 ACM SIGMOD Online | Publicly Available Database Software
Dr. Codd, known universally to his colleagues and friends--among whom I was proud to count myself--as Ted, was the man who, singlehanded, put the field of database management on a solid scientific footing.
Ted described it and explored its implications in a series of research papers--staggering in their originality--that he published during the period from 1969 to 1981.
Ted's achievements with the relational model should not be allowed to eclipse the fact that he made major original contributions in several other important areas as well, including multiprogramming and natural language processing in particular.

Codd started as a mathematician who did original work in self-reproducing automata (how to make a machine that can produce a copy of itself).
In 1969, Dr. Codd was a mathematician at IBM Research at the labs in San Jose, Calif., when he developed the relational model and wrote a paper for the 1970 June issue of the Communications of the ACM.
Codd later defined the basic normal forms and did for data what has been done for programming — added a sound mathematical foundation for proving correctness.

 Information Unbound #4 - by Erick Von Schweber - Infomaniacs
Ted Codd, then at IBM, realized that low level, procedural approaches were at the root of the applications and maintenance backlog, and devised the relational model of data to address the issue.
Ted was phenomenally successful, both in his analysis of the problem and in the development of a solution.
If Ted Codd was right in his assessment in the sixties - and he was very right judging by the unparalleled success of relational database and tool vendors and corporate America’s massive buy in - then this same assessment is even more valid today as we prepare to enter the next millennium.

But before Dr. Codd's work found its way into commercial products, electronic databases were "completely ad hoc and higgledy-piggledy," said Chris Date, a database expert and former business partner of Dr. Codd's, who was known as Ted.
Codd's idea, based on mathematical set theory, was to store data in cross-referenced tables, allowing the information to be presented in multiple permutations.
Codd is survived by his wife, of Williams Island; a daughter, Katherine Codd Clark of Palo Alto, Calif.; three sons, Ronald, of Alamo, Calif., Frank, of Castro Valley, Calif., and David, of Boca Raton, Fla.; and six grandchildren.

Codd's approach took a cue from first-order predicate logic, the basis of a large number of other mathematical systems, and was presented in terms of set theory leaving physical representation and access implementer-defined.
In June of 1970, Codd laid down much of his extensive groundwork for the model in his article, "A Relational Model of Data for Large Shared Data Banks" published in the Communications of the ACM, a highly regarded professional journal published by the Association for Computing Machinery.
In 1985, Codd, now president of the Relational Institute and with his own consultancy, put forth 12 basic rules plus nine structural, 18 manipulative and all three integrity rules, all of which had to be satisfied for a database to be considered fully relational.

Codd was the youngest of seven children born to a leather processor and his schoolteacher wife in the remote town of Portland, England.

 Ted Codd, Chris Date - IT Channel - IT Channel News by CRN and VARBusiness
Codd may not be a household name, but among those who know databases, he remains an icon a year and a half after his death.
Codd’s biggest single contribution to IT was the idea, described in published papers starting in 1969, that there must be a divorce between the physical and logical layers of the data system.
IBM had assigned Codd to a group examining approaches to the database problem, but since the computing giant had already come up with the hierarchical Information Management System (IMS), their work was restricted to hierarchical approaches, Sharon Codd recalls.
