Charles Bowers Momsen (June 21, 1896 – May 25, 1967), nicknamed "Swede", was born in Flushing, New York.
 He was an American pioneer in submarine rescue for the United States Navy, and he invented the underwater escape device later called the "Momsen lung", for which he received the Navy Distinguished Service Medal in 1929.
 In May 1939, Momsen directed the rescue of the crew of "Squalus" (SS-192).
RMS "Leinster" was a vessel operated by the City of Dublin Steam Packet Company, served as the Kingstown (now Dún Laoghaire)-Holyhead mailboat until she was torpedoed and sunk by German submarine "UB-123" on 10 October 1918, while bound for Holyhead.
 She went down just outside Dublin Bay at a point 4 nmi east of the Kish light.
 Over 500 people perished in the sinking – the greatest single loss of life in the Irish Sea.
The Italian sandwich, sometimes referred to as the Maine Italian sandwich, is an American submarine sandwich in Italian-American cuisine prepared on a long bread roll or bun with meats, cheese and various vegetables.
 The ingredients serve to counterbalance one-another, creating an equilibrium of flavors and texture.
 The Italian sandwich was invented in Portland, Maine, in 1903 by Giovanni Amato, a baker.
 It is known as a "submarine sandwich" or a "sub" in Boston, Massachusetts, and as a "spuckie" in East Boston.
Josef Papp (1933?
 in Tatabánya, Hungary – April 1989 in Daytona Beach, Florida) was an engineer who was awarded U.S. patents related to the development of an engine, and also claimed to have invented a jet submarine.
Kari Bruwelheide (born March 16, 1967) is an American archaeologist and anthropologist.
 She is known for her work as a physical anthropologist, bioarchaeologist, forensic anthropologist at the Smithsonian Institution's National Museum of Natural History.
 Since joining the Smithsonian in 1992, she has assisted Douglas W. Owsley, Division Head of Physical Anthropology, identify skeletal remains and determine the cause of death in various high-profile forensic cases.
 These cases have included studying the remains of three individuals discovered buried in the Chesapeake Bay area of St. Mary's City, Maryland, during a remote sensing survey at the foundation of the 17th-century Brick Chapel Catholic Church; examining and identifying the remains of victims of the siege on the Branch Davidian compound in Waco, Texas; examining the remains excavated in the historic Jamestown Colony; and assisting in the identification of American Civil War soldiers who perished aboard the "H. L. Hunley" Confederate submarine.
Charles A. Morris (1853 - March 8, 1914) was a Bloomfield, New Jersey engineer who owned his own dredging firm in New Jersey in the 1880s.
 Born in 1853, Morris came from a family of engineers and inventors.
 He invented a sliding bucket used for loading ships and other shipping devices.
 He helped the pioneering inventor John Philip Holland gain acceptance of his craft within the United States naval community.
 Mr. Morris was a good friend of the inventor and helped him out during a time when Holland was in financial trouble prior to the acceptance of The United States Navy's first commissioned submarine,  .
 Morris served as the shipyard superintending engineer on the submarine project from 1896-1897.
 The pioneering submarine was purchased by the United States Government on 11 April 1900.
H. L. Hunley, often referred to as Hunley, was a submarine of the Confederate States of America that played a small part in the American Civil War.
 "Hunley" demonstrated the advantages and the dangers of undersea warfare.
 She was the first combat submarine to sink a warship, although "Hunley" was not completely submerged and, following her successful attack, was lost along with her crew before she could return to base.
 The Confederacy lost 21 crewmen in three sinkings of "Hunley" during her short career.
 She was named for her inventor, Horace Lawson Hunley, shortly after she was taken into government service under the control of the Confederate States Army at Charleston, South Carolina.
HMS "H5", was a British "H"-class submarine of the Royal Navy.
 She was sunk after being rammed by the British merchantman "Rutherglen", mistaken for a German U-boat, on 2 March 1918.
 All on board perished.
A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch.
 A basic chronograph has an independent sweep second hand; it can be started, stopped, and returned to zero by successive pressure on the stem.
 Less simple chronographs use additional complications and can have multiple independent hands to measure seconds, minutes, hours and even tenths of a second.
 In addition, many modern chronographs use moveable bezels as tachymeters for rapid calculations of speed or distance.
 Louis Moinet invented the chronograph in 1816 for use in tracking astronomical objects.
 Chronographs were also used heavily in artillery fire in the mid to late 1800s.
 More modern uses of chronographs involve piloting airplanes, car racing, diving and submarine maneuvering.
American Diver, also known as the Pioneer II, was a prototype submarine built for the Confederate States of America military.
 It was the first successor to the "Pioneer".
 The "Diver" was invented and built by the same consortium that built the "Pioneer" in New Orleans.
 It was composed of Horace Lawson Hunley, James McClintock, and Baxter Watson.
 They were forced to move their operations to Mobile, Alabama following the capture of New Orleans by Union forces in April 1862.
 Although ultimately unsuccessful, it served as a model in the development of the consortium's next submarine, the "H. L. Hunley".
 The "Hunley" eventually became the first combat submarine to sink an enemy warship.

Question: Who invented the submarine abord which Kari Bruwelheide perished?
Answer: Horace Lawson Hunley
