The authorship of the following treatise is commonly attributed to Thomas Kempis. There seems no doubt that this must be a mistake, but it will not be out of place to begin with some account of him.
Thomas Hemercker was born at Kempen, near Köln, about the year 1380. His father was a labouring man, and his mother the village schoolmistress. At twelve years old he was sent to a religious community at Deventer called “The Brothers of Common Life,” and there studied grammar and plain chant. In 1399 he entered as a novice among the canons regular of Mount St. Agnes, near Zwoll, where his brother was prior.

He copied the Bible, the Missal, the works of St. Bernard. He was employed fifteen years in transcribing a Bible in four vols. , folio, which Rosweide saw in the library of the canons regular of Köln, with the following note which Kempis had appended:—“ Finitus et completus Anno Domini MCCCCXXXIX per manus fratris Thomae Kempis. ” He then began copying some pious and ascetic treatises, among them the Imitatio Christi .

He died in 1471.
The work has also been attributed to John Gerson the famous Chancellor of the University of Paris, who took so praiseworthy a part at
