Gregory Grassi was born in Italy in 1823, ordained in 1856, and sent to China five years later. Gregory was later ordained bishop of North Shanxi. With 14 other European missionaries and 14 Chinese religious, he was martyred during the short but bloody Boxer Uprising of 1900. Twenty-six of these martyrs were arrested on the orders of Yu Hsien, the governor of Shanxi province. All these martyrs were beatified in 1946, and were among the 120 martyrs canonized in 2000.
