Herbert Lockyer (1886–1984) was a minister and best-selling author of over 50 books, including the 21-volume "All" series.^[1] He was educated at Glasgow Bible Institute, afterwards receiving honorary degrees at Northwestern Evangelical Seminary, and the International Academy in London.^[1][2] He was most influential, however, after crossing the Atlantic to preach and write in the United States.

Dr. Lockyer was invited to preach at the 50th anniversary of the opening of the Moody Bible Institute, and this began his ministry in the United States.^[2] In the 1930s, the Institute published a number of his sermons, and Zondervan soon began to do the same. Dr. Lockyer also became influential in the Keswick Higher Life movement, ministering and publishing on both sides of the Atlantic. In his later life, his ministry was entirely focused on publishing, and his son, Herbert Lockyer, Jr., became his editor.^[1]

Billy Graham wrote, "Dr. Lockyer was unquestionably one of the spiritual giants of our century, and his prolific writings will continue to make an impact on countless Christians for generations to come if our Lord tarries."^[1]

Lockyer wrote the introduction to the Zondervan reprint edition of Ellicott's Commentary on the Whole Bible, (1959 and 1981) which he begins by saying, "As I journey back through almost half a century of Christian witness, of the many books that helped to shape my ministry, none has been so eagerly consulted as the volumes comprising Ellicott's Bible Commentary for English Readers, now known as 'Ellicott's Commentary on the Whole Bible.' This valuable eight-volume set is conspicuous among Commentaries for its adherence to the divine inspiration of Holy Scripture; its conservative approach to foundational truths; its comprehensive treatment of books, chapters and verses."^[3]
