(1823 Leagram, Lancashire – 1890 South Africa) was an English Jesuit priest, professor of Science and Director of Stonyhurst Observatory.
[2] After briefly managing St Marys Hall in Lancashire, he became Novice Master at Manresa House, Roehampton.
During this period, in 1862, he was the founding editor of the Jesuits' in-house magazine, Letters and Notices (still circulating in the new Millennium) and ensured The Month (a Catholic review) was edited by the Society.
The anonymous author of his obituary in Letters and Notices, wrote: "It is no exaggeration then to say that the literary work of the Province, so promising, so prolific, and so fruitful of good which has marked the last thirty years, is in great measure due to the initiatif and large-minded encouragement of Father Weld."
He spent the last three years of his life with the Zambesi Mission, having first directed operations from Rome and then going out himself to replace Henri Depelchin SJ to rescue the failed settlement, carry on missionary work and manage St Aidan's College in Grahamstown, (now Makhanda, Eastern Cape).
