David Jacobson was born in South Africa. He teaches in the Department of Sociology at Arizona State University. He received his PhD from Princeton University and studied at the Hebrew University of Jerusalem and the London School of Economics. His other books include Right Across Borders and Old Nations, New World. Allan Rennie was born in Stirling, brought up in Kilsyth and lives in Dunblane with his wife Margaret, a children's library assistant.
