Gerard van Velsen
Gerard van Velzen was lord of Beverwijk, Noordwijk, and Velsen.
He was the son of Albrecht van Velsen and Hildegonde. He was married to Machteld van Woerden, a sister of Herman VI van Woerden. In 1275, Van Velzen was named schout of Wijk aan Zee.
In 1296, Van Velzen conspired together with Herman VI van Woerden, Gijsbrecht IV of Amstel, Jan van Kuyk, and Arnold van Benschop to kidnap Floris V, Count of Holland. Eventually, together with Van Woerden and Van Amstel, they imprisoned the count in the Muiderslot. After Floris V attempted to escape, Van Velzen personally killed the count by stabbing him 20 times. Afterwards he fled to castle Kronenburg near Loenen aan de Vecht. A few days later, he was arrested and brought to Leiden to stand trial. There, he was tortured for three days before being quartered.
His motive for the murder was because of Floris' supposed rape of Van Velzen's spouse, after which she committed suicide.
