Shahzada Dawood, Wealthy Executive, Died With Son, Suleman, on Submersible

Shahzada Dawood, a British Pakistani businessman who was among the five people aboard a submersible journeying deep into the Atlantic to view the Titanic, was killed when the vessel imploded during its descent to the ocean floor, the authorities said Thursday. He was 48.

His 19-year-old son, Suleman, who was with him on the Titan submersible, was also killed.

Mr. Dawood was the vice chairman of Engro Corporation, a business conglomerate headquartered in the Pakistani port city of Karachi that is involved in agriculture, energy and telecommunications. His family is known as one of the wealthiest business families in the country.

His work focused on renewable energy and technology, according to a statement from his family.

Mr. Dawood was born on Feb. 12, 1975, in Rawalpindi, Pakistan. He studied law as an undergraduate at Buckingham University in Britain and later received a master’s degree in global textile marketing from Philadelphia University, now part of Thomas Jefferson University. In 2012, he was named a Young Global Leader by the World Economic Forum.

His son was a business student at the University of Strathclyde in Glasgow and had just completed his first year, a spokesman for the school said. Like his father, he was a fan of science fiction and enjoyed solving Rubik’s Cubes and playing volleyball, according to a statement from Engro.

“The relationship between Shahzada and Suleman was a joy to behold; they were each other’s greatest supporters and cherished a shared passion for adventure and exploration of all the world had to offer them,” the family’s statement said.

The pair’s shared passion for science and discovery, friends and family said, led them to embark on the expedition to the wreck of the Titanic.

Travel and science were “part of his DNA,” said Ahsen Uddin Syed, a friend of the elder Mr. Dawood who used to work with him at Engro.

A lover of “Star Trek” and “Star Wars,” Mr. Dawood was also fond of nature and often traveled to faraway places and shared pictures of his adventures, Mr. Sayed said.

His Instagram profile is like a memory book of his love of travel and nature; it is blanketed with photos of birds, flowers and landscapes, including a sunset in the Kalahari Desert, the ice sheet in Greenland, penguins in the Shetlands and a tiny bird in London with the caption “Dance of the Sugar Plum Fairy.”

“Don’t adventures ever have an end?” Mr. Dawood wrote in a Facebook post last year from a trip to Iceland, quoting Bilbo Baggins from “The Fellowship of the Ring.” “I suppose not. Someone else always has to carry on the story.”

Khalid Mansoor, another former colleague of Mr. Dawood’s, said that Mr. Dawood was a passionate champion of the environment. He was also a trustee at the SETI Institute, an organization devoted to the search for extraterrestrial intelligence.

In his role at Engro, the company statement said, Mr. Dawood advocated “a culture of learning, sustainability and diversity.” He was also involved in his family’s charitable ventures, including the Engro Foundation, which supports small-scale farmers, and the Dawood Foundation, an education-focused nonprofit.

“Shahzada’s and Suleman’s absence will be felt deeply by all those who had the privilege of knowing this pair,” his family’s statement read.

Mr. Dawood is survived by a daughter, Alina, and his wife, Christine.
