Frederic Dreyer

Admiral Sir Frederic Charles Dreyer (8 January 1878 – 11 December 1956) was an officer of the Royal Navy. He was known for his expertise in ship weaponry and created an important tool called a fire control system to help British warships aim better during battles.

Dreyer served as a key captain under Admiral Sir John Jellicoe during the big sea fight called the Battle of Jutland. His work helped sailors during important times in history.

He worked through two world wars before retiring as an admiral in 1943, after already stepping down once before. Dreyer's ideas and leadership made a lasting impact on how ships fought in those days.

Background and early life

Frederic Dreyer was born on 8 January 1878 in the Irish town of Parsonstown (now Birr) in King's County (now County Offaly). His father, John Louis Emil Dreyer, was an astronomer from Denmark and worked at the Armagh Observatory. Dreyer went to school at The Royal School, Armagh and then joined the Royal Navy in 1891. He studied at the Royal Naval College, Dartmouth.

Royal Navy career

Admiral Sir Frederic Charles Dreyer was a skilled officer in the Royal Navy. He did very well in his early studies and served on many ships, learning about naval guns and fighting. He wrote a book about doing well in sea skills tests and later became an expert in ship weapons.

During World War I, Dreyer served with Admiral Jellicoe and was the captain of the main ship at the Battle of Jutland. After the war, he held many important jobs, including leading groups of ships and helping plan naval battles. He retired in 1943 after serving through two world wars, having worked in many key roles for the navy.

Family life

On June 26, 1901, Frederic Dreyer married Una Maria Hallett. They had three sons and two daughters. His older brother, Major General John Tuthill Dreyer, worked with him on his inventions.

All three of Dreyer's sons and his two sons-in-law became naval officers. His second son, Vice Admiral Sir Desmond Dreyer, also became a gunnery officer and received a Distinguished Service Cross during the Battle of the River Plate. He later became Second Sea Lord.

Honours

In 1914, Frederic Dreyer received an award for his important work in helping ships aim their guns. After fighting in a big naval battle, he got another award for his leadership. Later, he received more awards for his service to the navy and the country.

Dreyer Fire Control Table

The introduction of centralized fire control for warships greatly improved how well ships could aim their guns. As naval guns could shoot farther, new methods were needed to control their fire. Over ten years, techniques like spotting where shells landed, using machines to calculate how quickly the distance to an enemy was changing, and long-range optical tools were developed.

The Royal Navy supported research into these methods, with two main groups working on them. One was led by Arthur Pollen, and the other by Dreyer. Both groups aimed to create a combined mechanical computer to help ships aim their guns better. The Royal Navy chose to use the Dreyer system, called the Dreyer Table, which became very popular in its final Mark IV* form.

With the addition of director control, ships could coordinate their guns much better. Most big Royal Navy ships had this system by mid-1916. The director was placed high on the ship where operators could see better than gun crews in the turrets. This helped improve aiming and allowed better estimates of where the enemy was when firing. However, longer shooting distances meant more complicated calculations. Although the Dreyer Table had some mechanical issues, it worked well overall. It was later replaced by the improved "Admiralty Fire Control Table" for newer ships, but Dreyer Tables were still used in World War II, especially in older British battleships and battlecruisers.

Published works

Admiral Sir Frederic Charles Dreyer wrote two books about sailing and the sea. His first book, How to Get a First Class in Seamanship, came out in 1900. Later, in 1955, he published The Sea Heritage: A Study in Maritime Warfare with Museum Press.
