Local leaders and residents showed up to a section of Rutland Road that will now be known as Dr. Lamuel Stanislaus Way.
The dedication took place right outside the home where Stanislaus lived for more than six decades.
Stanislaus was a dentist, community activist and UN ambassador for Grenada.
Those who asked that the street be renamed in his honor say that Stanislaus left behind a legacy serving Brooklyn.
Stanislaus died in 2016 at the age of 95.
