Masonic Lodges elect a member of the lodge each year to serve as the Master of the Lodge. He is the leading office bearer and responsible for the overall good running of the lodge and its affairs.
Despite popular myth, his title is simply "Master" - not Grand Master or any other variation. Although, when lodge members address the Master directly and in an official lodge setting they use the courtesy title "Right Worshipful Master" which has been handed down from old traditions and customs.
Masonic Lodges in countries all over the world do elect a Grand Master and he is responsible for how Freemasonry is practised within all the lodges in his own country. He has no authority over Masonic lodges in other countries.
Scotland is unique in that the head of Scottish Freemasonry is called the "Grand Master Mason" and not "Grand Master". This is because some of the oldest Scottish Masonic Lodges have documentary evidence linking them to the operative or working stonemason lodges which existed in the 16th Century and before. It is from these ancient operative stonemason lodges that modern Freemasonry bases much of their ceremonies and customs to this day.
Below is a list of the Master of Lodge St. John Fisherrow No 112. Sadly, much of our earliest records have been lost and the names of many Masters in the earliest years are as yet unknown.
