He helped write Apple Computer's Educational Classics, and produced the first electronic encyclopedia for personal computers, called The Discovery Encyclopedia.

Ron is editor of “Prophecy Central,” which is usually listed on the first page of Google searches for “prophecy” and “Bible prophecy.” He conducts “Prophecy Cafe” seminars and conferences.

His primary interests are in the areas of family (married to Barbara - three grown children), evangelism, discipleship, eschatology, apologetics, technology, and Israel.

Lambert Dolphin is a graduate of San Diego State University and Stanford University where he pursued studies in physics, electrical engineering and mathematics. He retired early after 30 years in research physics at a large west coast think tank and went on to pursue Bible teaching, research and writing.

After a long search through world religions and many years of restlessness about unanswered questions in life, Mr. Dolphin became a Christian in 1962. He studied under, and was greatly influenced by, the late pastor and Bible expositor Ray C. Stedman of Peninsula Bible Church in Palo Alto, California.

For more than 35 years he has maintained an active interest in the Middle East and Israel and he travels in that region often.

He edits the popular Internet site: “Lambert Dolphin’s Library.”

Lambert and Ron met over the Internet. Because of their strong common interest in biblical eschatology, similar evangelical beliefs and mutual commitment to sound biblical interpretation, they joined forces to write this book.
