from his autobiography, with additions by his wife Edna

After serving in the U.S. Army for three years in World War II, Dan In 1960, Dan graduated from Wheaton College, followed by a M. Div and Th. M. from Central Baptist Seminary, followed some years later by a research-master's degree in biology from Ohio University. He then taught for  five years at Wingate College in North Carolina, followed by seven years at Grace College in Indiana, where he helped to establish a standard biology department.

In 1973 he left full-time teaching to devote the remainder of his life to the study of sedimentary geology and the teaching of how it helps us to understand and appreciate the Biblical account of creation.

Betweem 1974 and 1977 he wrote the book God's Time-Records in Ancient Sediments to explain to Christians what the sedimentary rock layers of the earth are like, and why most of them required long periods of time to be deposited and converted into types of rock. In his own words,  "Helping Christians to learn this kind of information has been my primary work since 1973, and this work is needed more now than ever. Christians need to reject evolutionism, but when they reject true scientific discoveries they bring disgrace upon the Bible and Christianity."

Dan opposed the "misunderstanding which was being promoted by extreme creationist leaders in many of the Christian schools and colleges of the U.S. and Canada." His conclusions are found in his second book, Neglect of Geologic Data: Sedimentary Strata Compared with Young-Earth Creationist Writings, which he first published in 1987.

In both of these books, Dan was obsessed with ensuring the complete accuracy his assertions from geology, and he submitted his writings to the review of experts in the geologic field.

In addition to these two books, Dan also wrote a number of reviews and short papers, some of which are listed below.

Neglect of Geologic Data: Sedimentary Strata Compared with Young-Earth Creationist Writings.

Originally published in 1987, revised in 1993. Electronic edition (reproduced from the 1993 Edition) 2006.

"I find it unfortunate that, since the 1960s, a great many Christian teachers have neglected to take seriously the large array of evidences for long periods of time which are found in the sedimentary cover of the earth."  [From the Author's Statement]

Research Reports

Coral Reefs and Related Carbonate Structures as Indicators of Great Age
Abstract:  Evidence is abundant in the geologic literature that the earth is quite old, though typically overlooked or disregarded by young-earth creationists. Many large, biologically-built, in situ structures are found throughout the world in limestone and dolostone formations, such as modern and ancient coral atolls, the Grand Bahama Bank, and fossilized hardgrounds and stromatolites

Genesis 11 and Archaeological Evidence for Paleolithic Man
Abstract:  There are important reasons for attempting to see Genesis 11 and archaelogical data from Paleolithic peoples as compatible with each other. Abundant archaeological evidences for such people inhabiting both the Americas and Europe more than 10,000 years ago are surveyed, and it is suggested that these fit between the disastrous judgment of Babel and the birth of Abraham. Archaeological evidences for the true humanity of Neanderthal man are presented.

About IBRI:

The Interdisciplinary Biblical Research Institute is a group of Christians who see a desperate need for men and women convinced of the complete reliability of the Bible who will:
     (1) get training both in Biblical studies and in some other academic discipline, and
     (2) use this training to help other Christians deal with the many areas where non-Christian teaching is so dominant today.
We believe that such trained people can be effective in removing many stumbling blocks that keep others from the Gospel.
