Antonius de Heyde

Other name: 
Antony, de Heide
1646 in the Philippines
between 1690 and 1696

Physician from Middelburg

died in Amsterdam

De Heyde was one of the three Dutch people, along with Leeuwenhoek and Swammerdam, who published about their observations through single-lens microscopes. Toward the end of their lives, both De Heyde and Swammerdam abandoned their professional lives under the influence of the mystic Antoinette Bourignon.

In 1699, probably several years after his death in around 1695, De Heyde, George Garden, and Antoinette Bourignon are listed as authors of this English-language tract:

An apology for M. Antonia Bourignon: in four parts. I. An abstract of her sentiments, and a character of her writings. II. An answer to the prejudices raised against them. III. The evidences she brings of her being led by the spirit of God; with her answers to the prejudices opposed thereunto. To which is added, A dissertation of Dr. De Heyde, on the same subject. IV. An abstract of her life. To which are added, two letters from different hands, containing remarks on the preface to The snake in the grass and Bourignianism detected. As also, some of her own letters, whereby her true Christian spirit and sentiments are farther justified and vindicated; particularly as to the doctrine of the merits and satisfaction of Jesus Christ.
