Biography

Summarize
Perspective

Ralph Jeffery Slutz was born on May 18, 1917, in Cleveland, Ohio.

He received a Bachelor of Science in electrical engineering in 1938 and a Master of Science in 1939 from the Massachusetts Institute of Technology (MIT). Later, Dr. Slutz received his PhD in theoretical physics from the Princeton University in 1946.[6]

Dr. Slutz was associated with the Electronic Computer Project at the Institute of Advanced Study (IAS) following his PhD in 1946.[7] In 1948, he joined the National Bureau of Standards (now NIST), where he co-invented the SEAC computer with Samuel N. Alexander and worked as its chief architect until 1954. Dr. Slutz then served as the chief of the Radio Propagation Physics Division at the National Bureau of Standards in Boulder, Colorado, until 1980.[2][3][8][9][10]

Thumb
Ralph J. Slutz and Samuel Alexander worked on the SEAC Computer together in 1950.

After retiring from the National Bureau of Standards in 1980, he became a senior scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado at Boulder, where he led the ICOADS project until 1989. In 1987, Dr. Slutz co-authored and published the first research paper of ICOADS, titled A Comprehensive Ocean-Atmosphere Data Set. This first released dataset comprised seventy million marine datasets collected between 1854 and 1986. Since then, the datasets of ICOADS have been extended to the late 20th and early 21st centuries.[11][12]

Dr. Slutz died on November 16, 2005, in Boulder, Colorado. In 2010, The Ralph J. Slutz Student Excellence Award was established in the Computer Science Department at the University of Colorado at Boulder in his honor.[1][4]
