To the Sacred Memory of
Charles Mason
Surveyor - Astronomer - Scientist
April 1728 - October 25, 1786

English astronomer and surveyor who, with
Jeremiah Dixon, laid out the Mason-Dixon Line -
famous border between Maryland, Pennsylvania
and Delaware - using little but the stars from
God's Heavens, in the years 1763-1767.

Charles Mason was laid to rest at Christ Church
Burial Ground on October 26, 1786, in a plot
obtained by his good friend Benjamin Franklin
from Church Warden Tench Coxe. The location of
his grave in the burial grounds is unknown.

This original 1766 Pennsylvania-Maryland
boundary stone, quarried in England, stood for
two centuries upon the Mason-Dixon Line - and
now honors the memory of its surveyor,
Charles Mason.

This Plaque and Mason-Dixon Line Stone were dedicated
August 31, 2013, by Surveyors Historical Society and the
Mason-Dixon Line Preservation Partnership
on behalf of surveyors, astronomers and scientists everywhere.
