Malachi G. Sheahan II passed away peacefully on November 9, 2020 at his residence in Manhattan, at the age of 75.
Malachi, born to the late Margaret and Malachi Sheahan on December 4, 1944, was raised in the Bronx along with his three sisters. He graduated from the St. Helena School and Saint Michael’s College.
On July 3, 1968 Malachi married Danielle Dwyer at Our Lady of Mercy Church, followed by a reception at Tavern on the Green in Central Park.
His first profession was as a teacher, and in many ways he remained one throughout life. He was always ready to impart some historical knowledge or to provide an impromptu science lesson. Yet mostly, he taught by example.
In the 1970s he began his career with the FAA where he worked in various locations from NY to DC and made a number of lifelong friends. His 15 minutes of fame came on New Year’s Eve 1999 as national networks covered his work on the Host and Oceanic Computer System Replacement (HOCSR) program for the FAA’s Y2K readiness efforts. He retired from his management role in National Airspace Implementation and System Requirements in 2006 to care for his wife, Danielle, but continued to consult on aviation projects both domestically and abroad.
He was a man of diverse interests — a fervent sports fan, a music lover, a history buff, a voracious reader and devoted father, brother, uncle, cousin and friend. Unequivocally, his most cherished role was as “Papa” to his five beloved grandchildren who eagerly explored the city’s subways, museums, zoos, restaurants and parks along with him.
NYC, “the known center of the universe”, was his eternal love — from its sports teams to its arts, history, institutions and most of all its people. While he was a frequent and avid traveler, NYC was always home. Fittingly, he passed away just blocks from his place of birth on the island of Manhattan.
Malachi is survived by his children and their spouses, Claudie and Malachi G. Sheahan III and Bree Sheahan and Scott Twibell; his grandchildren Malachi G. Sheahan IV, Connor Sheahan Twibell, Shea Danielle Twibell, Jack Duncan Sheahan and Luke Daniel Sheahan; his sisters Kathleen (Kate), Margaret (Maggie) and Constance (Connie) and brothers-in-law Gene McCarthy and Philip Guido; and many dear nieces, nephews, cousins and friends.
In his memory, Malachi would likely suggest you spend your money doing something with the people you care about. For those who wish, gifts in his memory may be made to: The Danielle and Malachi Sheahan Memorial Scholarship Fund at LSU. This fund was established to support female and underrepresented minority medical students in the field of Vascular Disease. Or The Bronx Community Relief Effort in Memory of Malachi Sheahan. Donations will help address the dire gap many students in the Bronx face in accessing the technology and connectivity they need to succeed in school.
