Dietrich Loer (L’Orer), OCart. – Carthusian, born in Hoogstraeten (Antwerp) c. 1490, died in the Charterhouse of Würzburg on 26 August 1554. He entered the monastery at Cologne in 1518, where he was followed by his brothers Bruno and Hugo, drawn by his example. In 1530 he succeeded Lansperg as vicar and in the same year was elected prior of the Charterhouse of Hildesheim.
By this time he was already renowned throughout Europe for his leading role in the publication of the works of Denis the Carthusian. In 1543 he was elected prior at Buxheim and visitor of the Lower German province. Charles V chose him as his confessor; bishops, princes, and great lords sought his counsel.
Among the editions of others’ works and his own compositions or translations, the following deserve mention:
1) Dionysii Cartusiani... fidissimus catalogus (Cologne 1530, 1532);
2) Monotesaron, idest unum continuum Evangelium quatuor Evangelistarum (ibid. 1531, 1546, 1586);
3) Praestantissima quaedam miracula, quae Bruxelles... circa venerabilem Eucharistiam, fiunt (ibid. 1532);
4) Die groote evangelische Peere, etc. (Utrecht 1535; Antwerp 1539, 1639), a work of piety composed by a female servant of God and first published by Loer;
5) Psalterium latinum et germanicum fideliter traductum (Cologne 1535, 1536, 1562);
6) Theologiae mysticae... lucida demonstratio (ibid. 1569).
