Wink Gross
Winthrop A. "Wink" Gross (? – ?) is a retired Tektronix engineer.
Wink started at Tektronix as a summer student from Harvard in 1968 and became a full time Tek employee upon graduation with a BA in EE in 1969. He worked closely with Carl Battjes for a number of years during the 454 design, and designed the 485 portable oscilloscope's main vertical amplifier.
He left Tek to go to MIT for their graduate Engineer degree in 1972 and 1973, returning to Tek to work on the main vertical amplifier of the 7104, 1 GHz oscilloscope. Gross and John Addis collaborated closely on both the 485 and 7104.
Wink went to the Portable Instrument Division in 1979 and became vertical system engineer for the 2465. He designed the 2465 main vertical amplifier, the channel switch, and the auxiliary input preamp. Marv LaVoie designed the 2465 attenuator.
Ken Schlotzhauer (who died in China in an auto accident May 30, 1995) designed the 2465 trigger IC and Mike Metcalf (who died of Hodgkin's Lymphoma complications April 1, 1989) designed the 2465 Z axis IC, both under the direction of Art Metz. Art had horizontal system responsibility and designed the non-IC part of the horizontal as well.
Wink went to the IC department in 1982 as Analog IC Design Manager, eventually becoming Engineering Manager for the Microelectronics Group. In 1994, when Tektronix sold its IC facility to Maxim Integrated Products, Wink went with Maxim as Director of High Frequency IC Design. He retired in 1999.
