Born in Kraków, Poland, he emigrated to Canada at an early age. He lived in Luseland and Winnipeg before moving to Sweden in 1975. Jack commenced his career as freelance photographer in 1982. His first larger project was documenting the work of Swedish consultants VBB, now Sweco, in Egypt as they studied tombs in the Valley of the Queens and other Egyptian monuments in order to devise a plan of action to save them from saline corrosion.

In 1984 he began work as a staff photographer at the Swedish national daily newspaper Svenska Dagbladet and was accepted as a member of the picture agency Tiofoto. His international assignments included, among others, a feature on UNDP missions in Mali and Burkina Faso and coverage of the refugee situation after the Iran–Iraq War in 1988 for the Swedish Red Cross.

In 1991 he joined the staff of Pressens Bild, now Scanpix, picture agency. He specialised in news, and sports photography covering most major sports events, including 6 Olympic Games.

Since 1990 he has been the recipient of numerous national and international honors, such as the 2001 Fuji European Sport Photographer of the Year award.^[1] In 2002 his black and white portfolio portraying swimmer Emma Igelström placed first in the competition by French sports newspaper L'Équipe and the International Olympic Committee (IOC).

Jack is currently employed as staff photographer at Dagens Industri, a daily business newspaper based in Stockholm Sweden. He is also collaborating as official photographer for the Swedish Olympic Committee^[2] and as a consultant on business photography for Activated Logic, Australia.
