[3] After his graduation in 1866, Greene enrolled into National Deaf-Mute College (now Gallaudet University) on September 12, 1866, to pursue a Bachelor of Arts (B.A.)

Throughout the memoir, it shows that Greene embraces the bilingual education philosophy and a big believer of connecting with his students to build trust first before he begins his teaching.

Samuel Thomas Greene died on February 17, 1890, at the age of 46 at his family home in Belleville, Ontario after an ice yachting accident on the Bay of Quinte.

Greene was an avid ice-boating yachtsman and he regularly took his pupils, staff members and friends on many sails on the Bay of Quinte.

Due to the rapid speed and miscommunication, Greene was thrown out from the boat and flew ten feet through the air and hit his head on the ice with a strong force.

The news of his death devastated many people in Belleville, especially the staff members and pupils at the Ontario Institution for the Education of the Deaf and Dumb.

The Ontario Institution held the funeral service for him two days later on February 19, 1890, and everyone at the school wore badges to pay their respect for the memory of him.

Located in the Section P of the Belleville Cemetery, his tombstone has an engraving of his last name "Greene" in manual alphabet of American Sign Language.

The Ontario Heritage Foundation unveiled a commemorate plaque to honor Greene's achievements during the 125th anniversary celebration of Sir James Whitney School of the Deaf on July 1, 1995.
