Pierre Gerard<br />
Pierre Gerard, founder and presid<strong>en</strong>t<br />
of 2iE (LeMans, France), rec<strong>en</strong>tly<br />
passed away. Gerard was dedicated<br />
to expanding the use of mechanized<br />
irrigation throughout the world. Under<br />
his leadership, 2iE’s c<strong>en</strong>ter pivot and<br />
linear move irrigation systems have<br />
be<strong>en</strong> used in France and exported to<br />
doz<strong>en</strong>s of countries. He was virtually<br />
an institution in the European c<strong>en</strong>ter<br />
pivot and linear move market for over<br />
40 years. He was a true innovator with<br />
many of his ideas still being used today. Pierre was the first to<br />
introduce water drive c<strong>en</strong>ter pivots into Europe in 1964-1965.<br />
In 1969, he introduced the first electrically powered system in<br />
Europe. Later that year he started manufacturing the first c<strong>en</strong>ter<br />
pivot wheel gear box in Europe. In 1976 he received a pat<strong>en</strong>t on<br />
his unique towable wheel gear box. This gear box allowed you<br />
to dis<strong>en</strong>gage the worm shaft. This concept is still being used on<br />
c<strong>en</strong>ter pivots today. Other pat<strong>en</strong>ts he held were for a towable<br />
linear move system which was capable of pivoting at the <strong>en</strong>d<br />
of the field and the original drive line universal joint. Pierre<br />
dedicated his life to expand the use of mechanized irrigation<br />
around the world. 2iE will continue to promote Pierre’s vision.<br />
S<strong>en</strong>ninger remembers Dale Heermann<br />
Dale F. Heermann, 71, passed away in February. Dale was born and raised in Nebraska. He received his B.S. in<br />
Agricultural Engineering from University of Nebraska. After graduation, he <strong>en</strong>tered the U.S. Air Force. After his<br />
military service Dale att<strong>en</strong>ded CSU receiving his M.S. and PhD in Agricultural Engineering. Following graduation he<br />
began his long career with the USDA Agricultural Research Service. He retired from the USDA ARS in 2005 after a<br />
very satisfying and productive career.<br />
Dale developed the mathematical formulation to describe the hydraulics of c<strong>en</strong>ter pivot irrigation systems and<br />
developed a computer program for pivot evaluation and design that is incorporated into the USDA Natural Resources<br />
Conservation Service national toolbox. He also developed the methodology for computing uniformity of irrigation<br />
by c<strong>en</strong>ter pivots, which is incorporated into both U.S. and international industry standards. Dale pioneered computer<br />
irrigation scheduling technology for c<strong>en</strong>ter pivots based on local weather data and irrigation application. He was a<br />
leader in promoting improved irrigation managem<strong>en</strong>t worldwide.<br />
Dr. Heermann had more than 150 technical publications, and made more than 100 technical pres<strong>en</strong>tations at national and international meetings<br />
as an authority on c<strong>en</strong>ter pivot irrigation and precision farming. He was the recipi<strong>en</strong>t of numerous awards including the <strong>Irrigation</strong> Association as<br />
“Man of the Year” in 1985. The ASABE, in 2007, <strong>en</strong>dowed the Heermann Sprinkler Award in his name to be awarded annually.<br />

dealer school<br />
in Grand Island, Nebraska<br />
Although the weather was not nice, it couldn’t keep<br />
some dealers from att<strong>en</strong>ding the rec<strong>en</strong>t dealer school.<br />
Folks were able to receive information about sprinklers,<br />
applications, effici<strong>en</strong>cies, product installation, meters,<br />
boom systems, trouble shooting and other topics. One<br />
lucky att<strong>en</strong>dee, Gary Fiscus of Quality <strong>Irrigation</strong> in Yuma,<br />
Colorado, won a free sprinkler package with a retail value<br />
up to $5,000. Watch for more details about upcoming<br />
schools throughout the year.
