TITLE: Ralph C. Brendle Collection

COLLECTION NUMBER: B2014.028

OVERVIEW OF THE COLLECTION

Dates: 1970-1976

Extent: 5 boxes; 1.3 linear feet

Language and Scripts: The collection is in English.

Name of creator(s): Ralph C. Brendle, Alyeska Pipeline Service Company

Administrative/Biographical History:
Ralph C. Brendle was born December 13, 1912 in Colorado. He graduated from the University
of Colorado in 1941 with a degree in architectural engineering. He served with the United
States Navy from 1941-1946. After leaving the service, he worked for the Bureau of
Reclamation in Colorado and North Dakota. In 1954, he moved to Hawaii to help found
Terminal Steel with Ray Ortiz. Returning to the Bureau of Reclamation in 1958, he worked in
North Dakota, Utah, and Nevada before relocating to Alaska to work on the Trans-Alaska
Pipeline. Throughout his career, he maintained a side business doing tile work.

Ralph married Mabel Ledelle Lathan in 1938. They had four children: Frank Brendle, Sally
(Paul) Fillo, Bette Hess, and Becky Nidiffer. Ralph died on January 8, 2004.

Scope and Content Description:
The collection consists of 532 color 35mm slides and 610 color photographic prints created or
collected by Ralph Brendle during his work on the construction of the Trans-Alaska Pipeline in
the 1970s. Included are 62 of 80 slides intended to accompany the script, “General Slide
Presentation,” developed by Alyeska Pipeline Service Company. The images in the collection

illustrate numerous aspects of pipeline planning and construction. Of particular note are
images of the construction of the E.L. Patton Bridge over the Yukon River in 1974-1975, as well
as several images of the Davidson Ditch.

Arrangement: Arranged by format in two series: 1. 35mm slides. 2. Prints. 3. Publications.
Further arranged by Brendle’s own index numbers when known, and then by date when
known.

Notes
For many of his photos, Brendle used the same alphanumeric indexing system as other TAPS
engineers; these images can therefore be compared for additional contextual information.
Abbreviations used by Brendle include:
P.S. = pump station
D.S. = disposal site
V.S.M. = vertical support member
C.L. = center line
