Bernard Howell Leach, CBE, CH (5 January 1887 – 6 May 1979), was a British studio potter and art teacher. He is regarded as the "Father of British studio pottery"

Leach was born in Hong Kong and brought up in the Far East. His father was a colonial judge in Hong Kong and his maternal grandparents were missionaries in Japan. As a young man he studied etching at the London School of Art before settling in Japan where he became fascinated with pottery and studied under the great master Kenzan.

Leach was born in Hong Kong, but spent his young adult years in Japan where he came into contact with a group of young Japanese art lovers who called themselves Shirakaba (白樺). Through them he learned about William Morris and the Arts and Crafts Movement.

It was in Japan that Leach began potting under the direction of Shigekichi Urano (Kenzan VI) and befriended a young potter named Shoji Hamada. With Hamada, he set up the Leach Pottery at St. Ives, Cornwall in 1920, including the construction of a traditional Japanese wood burning kiln. The two of them promoted pottery as a combination of Western and Eastern arts and philosophies. In their work they focused on traditional Korean, Japanese and Chinese pottery, in combination with traditional techniques from England and Germany, such as slipware and salt glaze ware. They saw pottery as a combination of art, philosophy, design and craft – even as a greater lifestyle. However, many in the West considered their pottery crude by the refined standards of the day. Publishing A Potter's Book in 1940 defined Leach's craft philosophy and techniques, and became his breakthrough to recognition.

July 3, 1978) is an American musician from Providence, Rhode Island, and is best known as being the current lead vocalist of Killswitch Engage and also for being the vocalist for the blues rock band Seemless.

In February 2012 he rejoined Killswitch Engage following the departure of vocalist Howard Jones in January 2012.

Leach's first band, Corrin, was formed in the early 1990s. Corrin recorded four songs in 1996 which were eventually released as a CD by Propaganda Machine in 1998 after the band's breakup.

Leach's second band, Nothing Stays Gold, formed in the mid-90s. They put out a single ep before splitting in 97/98.

Meanwhile, some remaining members of Overcast and Aftershock were forming a new band in the Massachusetts area and were seeking a vocalist. In 1999, Leach joined bassist Mike D'Antonio, guitarist Joel Stroetzel, and drummer Adam Dutkiewicz to form Killswitch Engage. Their self-titled debut was released on July 11, 2000.

Carlton Leach (born 1959) is an author, occasional actor and a former criminal.

He was born in Canning Town in East London. Leach was catapulted into a criminal career by his love of West Ham. Before long, he was a member of the notorious Inter City Firm, a gang of hooligans who followed the East London club.

He started work as a bouncer in East London, where he became involved with Pat Tate and Tony Tucker, both of whom worked as large scale dealers in ecstasy during the rave era in the late 1980's.

Three of the gang, Pat Tate, Tony Tucker and Craig Rolfe, would eventually meet an abrupt and bloody end in December 1995, when they were shot to death in a Range Rover on a farm track in Rettendon, in what are known as the Triple Rettendon Murders.

In 2003 he wrote a memoir about his criminal exploits entitled Muscle. In 2007 a film based on the book was released entitled Rise of the Footsoldier starring Ricci Harnett as Leach.

A father of six children, he resides with his family in Hutton, Essex.
